Helmet use among users of the Citi Bike bicycle-sharing program: a pilot study in New York City.
Article in Journal of community health, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The use of bicycle helmets to prevent or reduce serious head injuries is well established. However, it is unclear how to effectively promote helmet use, particularly in the context of bicycle-sharing programs. The need to determine rates of helmet use specifically among users of bicycle-sharing programs and understand if certain characteristics, such as time of day, affect helmet use, is imperative if effective promotion and/or legislative efforts addressing helmet use are to be developed. We estimated the prevalence of helmet use among a sample of Citi Bike program users in New York City. A total of 1,054 cyclists were observed over 44 h and across the 22 busiest Citi Bike locations. Overall, 85.3% (95% CI 82.2, 88.4%) of the cyclists observed did not wear a helmet. Rates of helmet non-use were also consistent whether cyclists were entering or leaving the docking station, among cyclists using the Citi Bikes earlier versus later in the day, and among cyclists using the Citi Bikes on weekends versus weekdays. Improved understanding about factors that facilitate and hinder helmet use is needed to help reduce head injury risk among users of bicycle sharing programs.
