Additionally, Elvik combined effect sizes for head, face and neck injury into one analysis while again adjusting for publication bias using the trim-and-fill method. For example, the assessment of publication bias requires an independent review of the research literature by two bike helmets and types of injuries, and this is not possible when there is a sole author. Further, the protective effect for head, hrlmets and neck injuries were assumed to be identical, although there is no evidence that helmets affect different injuries in the same manner.

Importantly, such heterogeneity among effect sizes for different body locations could be the cause of funnel plot asymmetry, and not publication bias.

Third, the use of the tupes method anr adjust for publication bias is usually not recommended. Additionally, the journal published two full-length corrections due to data and analytical errors.

In sum, the research literature on bicycle helmet effectiveness was last systematically reviewed by Attewell and colleagues inskate helmet size past reviews have been criticized for methodological weaknesses and did not account for sources of bias. Therefore, the objective of this study was to conduct an updated systematic review and meta-analysis of studies bike helmets and types of injuries bkke whether helmet use mitigates head, serious head, face, neck and fatal head injury.

If publication or time trend bias is detected, appropriate adjustment methods will be used. An initial search was performed on 2 Februarywhich was updated 26 January Full-text, English language studies were included if injuries were medically diagnosed i.

When two or more studies include data from the same source, the study with the most complete data was included. Study bike helmets and types of injuries were contacted if relevant data were not published but the study met other criteria. When published abstracts met other inclusion criteria, a search was conducted for a full-text report of the study and the authors were womens purple bike helmet. Bike helmets and types of injuries research librarian was consulted before the search for articles.

The data were categorized as relating to head, serious head, face, neck or fatal head injuries. Head, face or neck injuries were of any severity. Concussions in isolation were not considered serious head injuries, as they are usually less than AIS3. Cycling fatalities with multiple injuries including the head were categorized as a head injury.

Whenever possible, cyclists wearing unapproved, no bike helmets and types of injuries, foam or leather helmets bike helmets and types of injuries excluded and controls were limited to those injured solely below the neck.

The information extracted from each study included the number of injured cyclists available for analysis, the number of cases and controls by helmet use, the country where data were collected, whether the data were collected prospectively or retrospectively, age categories of cyclists included all, child or adultthe proportion of missing helmet data, the proportion of males, the proportion of motor vehicle collisions and whether injuries to the head, face or neck were included in the controls.

A series of hierarchical random effects meta-regression models were fit for the log odds ratio using all extracted data. Before analysis, 0. Model 1 was a baseline model with no moderators, Model 2 included injury type as a moderator, Model 3 included bike helmets calgary random effect for study and Model 4 included a random effect for injury type.

The use of multivariate meta-regression methods allows the analysis to consider the injured cyclist as a whole as opposed to individual body regions. Publication bias was inspected visually using funnel plots and formally tested using the rank correlation test.

Time trend bias was inspected visually using cumulative forest plots and formally tested by including year as a covariate centred atthe year of the last included study. All statistical analyses were performed using the R metafor package.

Characteristics of the studies included for the meta-analysis are given in Table 1. The included studies span 28 years —16 representing four continents Asia: Data were collected prospectively in 23 studies and retrospectively in The reported injuries typs diagnosed in: Table 1.

Characteristics of studies meeting selection criteria. The results from the random effects womens fox mountain bike helmets models are given in Table 2. Model 4 was chosen as the final model which includes injury type bike helmets and types of injuries a moderator and random effects for injury type by study.

The inclusion of each model component greatly improved model fit.

Study-level moderators for pink riding helmet bike helmets and types of injuries data were collected, setting for data collection, prospective or retrospective data collection, an indicator for mandatory helmet legislation for data collection jurisdiction, age category, proportion of males onjuries proportion of cyclists in a motor vehicle collision were individually added to Model 4.

None of these moderators improved model fit or substantially modified estimates of helmet tyoes by injury type. Table 2. Summary of meta-analysis models.

Venn diagram of included studies from systematic reviews or meta-analyses of red and black street bike helmet helmet effectiveness. This study differs from previous reviews and meta-analyses in several ways. Due to criticisms of the Cochrane Review, minimal selection criteria were chosen similar to Attewell and bike helmets and types of injuries however, medically verified injuries were required to minimize injuriies influence of bias in self-reported data.

This eliminated three studies included in other reviews. To assess the influence of excluded studies, the final multivariate meta-regression model was refit including the three studies with self-reported injury data and the German language study. The summary odds ratios for each injury bike helmets rating changed very little see Table A1available as Supplementary data at IJE online.

Table 3 contrasts the current results from those in previous meta-analyses. With regards to head injury of any severity, the current results are most similar to Elvik.

However, no evidence of time trend bias was found and tjpes summary results change very little if the analysis is restricted bike helmets and types of injuries studies published in the past 10 years see Table A1available as Supplementary data at IJE online.

Each year over , children are injured in bicycle-related accidents. set up to establish strict requirements for the manufacturers of all types of helmets.

Table 3. Elvik was highly critical of the inclusion criteria used in the Cochrane Review and suggested sensitivity analyses be performed to assess its impact on the summary measures. Since the inclusion criteria of this review were more similar to Elvik, the final model was refit only on studies most sold bike helmets collected data prospectively, which is similar to the Cochrane Review.

With the exception of studies with fatal head injury which collected bike helmets and types of injuries retrospectively, the summary estimates were similar to the final model see Table A1available as Supplementary data at IJE online. Fatal head injury was not included in previous meta-analyses, but the current estimate is similar to that reported by Attewell and colleagues for fatal versus non-fatal injury by helmet use.

With bike helmets and types of injuries exception of the summary estimate for head injury, the current results run counter to the most recent meta-analysis by Elvik. No strong evidence was found of either publication or time trend bias. There is some visual evidence of funnel plot asymmetry, but this is due to two studies with small sample sizes rate bike helmets therefore has little to no impact on the analysis.

The summary odds ratios were nearly identical to the final model see Table A1available as Supplementary data at IJE online. Therefore, it is possible typed previously identified biases are partly an artefact of not performing a systematic search for studies.

Bike helmets bontrager, protective effects associated with helmet use were found for serious or fatal head injuries which were not included by Elvik. This suggests that helmets affect head, face and neck injuries differentially, thereby invalidating any overall summary measure that combines these bike helmets and types of injuries.

In a series of commentaries inthe Cochrane Review was criticized for not accounting for risk compensation. Since this ugliest bike helmets, there has been very little published research on the topic and no systematic injjries.

With regards to this injurkes, adjusted summary estimates are not possible without study-level data on risk compensation, irrespective of whether the hypothesis is supported by evidence. bike helmets and types of injuries

bike helmets and types of injuries The results from two recent, large studies do shed some light on the risk compensation hypothesis. Amoros and colleagues used multivariable logistic regression models to adjust for several factors including injury severity score for injuries below the neck as a proxy for crash severity. These results suggest helmsts an adjustment for risk compensation is difficult due to a lack of data and such an adjustment may also be unnecessary.

Helmet his meta-analysis, Elvik found that helmet use was associated with increased odds of neck injury; however, the inclusion of more kids bike helmets brings those results into question. Additionally, the hepmets of the literature found that neck injury is not common and usually of low severity. From data found in the publication or provided by the authors, the proportion of neck injured cyclists was 2.

Across all studies, the proportion bike helmets and types of injuries cyclists with neck injuries 2.
