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

backgroundChina implemented the 'One Helmet, One Belt' road safety campaign in April 2020 to improve helmet use among cyclists and motorcyclists. We evaluated its long-term effect.

methodsWe analysed crash data from 379 media sources that reported at least one road traffic crash per quarter between January 2019 and September 2024, as indexed by the Automated Road Traffic Crash Data Platform. The proportion of media-reported crashes involving helmeted motorcyclists and cyclists was compared before and after implementation of the national campaign. We calculated adjusted (aORs) using logistic regression, controlling for season and the COVID-19 pandemic period and fitted Joinpoint regression models to identify periods with significant changes.

resultsAmong 20 546 media-reported crashes involving motorcyclists and cyclists, the overall proportion of riders wearing helmets increased significantly following the campaign's implementation (aOR: 2.37; 95% CI: 2.08 to 2.72). However, this increase emerged only in the first 8 months of the campaign (April-December 2020), after which proportions plateaued. Subgroup analyses detected distinct temporal patterns for motorcyclists (an initial increase followed by decline), professional delivery riders (no significant trends) and publicly shared vehicle riders (consistently increasing trends).

conclusionsOur study documents an initial increase followed by stabilisation in proportion of media-reported crashes involving helmeted motorcyclists and cyclists following the national injury prevention campaign. The intervention's effectiveness varied across rider subgroups. These findings underscore the importance of sustaining and enhancing the national campaign while developing targeted interventions for distinct user groups in China, also suggesting similar initiatives might be effective in other international contexts.
