The correlation between sanction adjustments and drunk-driving violations and related outcomes in Taiwan: A nationwide interrupted time series analysis.

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
BACKGROUND AND
aimsDrunk-driving accounts for a significant portion of traffic crashes in Taiwan. From 2008 to 2013, both the Taiwan Legislative Yuan and the federal administrative agencies collaborated to increase drunk-driving penalties. This study aimed to determine whether these sanction changes are associated with changes in the incidence of drunk-driving and subsequent hospital admissions.
designExploratory retrospective cohort study.
settingTaiwan.
participantsAll traffic crashes involving drunk-driving violations and every involved individual from 2003 to 2019 in Taiwan. MEASUREMENTS: Interrupted time series analysis (ITSA) method was used to examine the effects of the three policy interventions in January 2008, December 2011 and June 2013. The numbers of drunk-driving crashes, drunk-driving casualties, drunk-driving-related admissions, drunk-driving-related major traumas, drunk-driving-related deaths and drunk-driving-related medical expenses in different time segments were compared to evaluate the effect of each policy intervention. All three policy initiatives increased drunk-driving penalties, and there were no intervening policy changes that reduced said penalties.
findingsFrom January 2003 to January 2008, the numbers of all drunk-driving-related outcomes gradually increased. After the first penalty adjustment, the reported number of drunk-driving crashes had a sudden decrease (1632 in January 2008 to 1374 crashes in February 2008, β
conclusionsIncreasing the fine and maximum incarceration periods for drunk-driving in Taiwan appears to be associated with a reduction of the number of drunk-driving crashes and other related outcomes; however, the decrease in drunk-driving crashes diminished over time, especially after the third sanction change in 2013.
