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

objectiveTo assess the effect of a demerit points system, introduced in Italy in July 2003, on the prevalence of seat belt use (intermediate outcome) and the number of road traffic deaths and injuries (health outcomes).

designPre- and post-intervention regional observational study for seat belt investigation (April 2003, October 2004); national time-series analysis of road traffic deaths and injuries between 1999 and 2004 for health outcomes.

settingVeneto region, Italy.

participants19,551 drivers, 19,057 front passengers and 8,123 rear passengers estimated to be aged over 11 years were included in the investigation into seat belt use. 38,154 fatalities and 1,938,550 injured subjects were examined for the time-series analysis.

interventionsDemerit points system.

main outcome measuresThe proportions of drivers and front and rear passengers observed to be using seat belts before and after the intervention; estimates of lives and injuries saved through the implementation of a penalty points system.

resultsThe demerit points system was followed by an increase in observed seat belt use of 51.8% (95% confidence interval 48.7% to 54.9%) among drivers, of 42.3% (95% confidence interval 39.2% to 45.5%) among front passengers and of 120.7% (95% confidence interval 99.4% to 144.3%) among rear passengers. It is estimated that 1,545 (95% confidence interval 1387 to 1703; p<0.0001) deaths and 91,772 (95% confidence interval 67,762 to 115,783; p<0.0001) injuries were prevented in the 18 months after the introduction of the legislation, i.e. an 18% reduction (1545/8570) in fatalities and a 19% reduction (91,772/473,048) in injuries.

conclusionsThe demerit points system is effective both in encouraging drivers and passengers to adhere to the law and in terms of health outcomes, substantially contributing to road safety.
