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

The goal of our study is to understand the impact of Tobacco 21 (T21) laws on youth smoking and health equity. We conducted modified Poisson regression models using 2014-2019 Monitoring the Future data to measure the impact of attending school in a county 100% covered by a T21 law versus counties with <100% T21 coverage on past 30-day smoking participation (n = 262,632), first cigarette smoking initiation (n = 189,698), and daily smoking initiation among 8th, 10th, and 12th graders (n = 214,496), separately. Additive interactions were tested between T21 coverage and sex, race/ethnicity, parental education, and college plans. T21 coverage was associated with a lower likelihood of smoking participation among 12th graders. T21 coverage was most strongly associated with a lower likelihood of smoking participation among: Hispanic and NH (Non-Hispanic) Other/Multiracial individuals; respondents with parents who had less than a college education; and respondents who were not definitely planning on attending college. T21 laws were associated with a lower likelihood of smoking participation among 12th graders. T21 policies were most impactful for individuals disproportionately impacted by tobacco, indicating T21 laws might help reduce tobacco-related health disparities.
