1 · What the graph read from 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.

2 · The registry

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

objectiveThe purpose of this study was to describe bicycle helmet use among Montreal cyclists as a step towards injury prevention programming.

methodsUsing a cross-sectional study design, cyclists were observed during 60-minute periods at 22 locations on the island of Montreal. There were 1-3 observation periods per location. Observations took place between August 16 and October 31, 2011. Standard statistical methods were used, unadjusted and adjusted odds ratios and 95% confidence interval were calculated.

resultsA total of 4,789 cyclists were observed. The helmet-wearing proportion of all cyclists observed was 46% (95% CI 44-47). Women had a higher helmet-wearing proportion than men (50%, 95% CI 47-52 vs. 44%, 95% CI 42-45, respectively). Youth had the highest helmet-wearing proportion (73%, 95% CI 64-81), while young adults had the lowest (34%, 95% CI 30-37). Visible minorities were observed wearing a helmet 29% (95% CI 25-34) of the time compared to Caucasians, 47% (95% CI 46-49). BIXI (bike sharing program) riders were observed wearing a helmet 12% (95% CI 10-15) of the time compared to riders with their own bike, 51% (95% CI 49-52).

conclusionsAlthough above the national average, bicycle helmet use in Montreal is still considerably low given that the majority of cyclists do not wear a helmet. Injury Prevention Programs could target the entire cyclist population, but special attention may be warranted in specific groups such as young men, visible minorities, BIXI riders, and those riding in tourist areas. Additionally, a collaborative enterprise with the bicycle sharing system BIXI Montreal™ could prove to be fruitful in addressing the availability of bike helmets for BIXI riders.
