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

backgroundEvidence of US adult flavored e-cigarette use prevalence stratified by age, smoking status, and purpose for vaping (ie, quitting smoking, to use when or where smoking is not allowed) can inform policies that reduce the tobacco-related cancer burden.

methodsCurrent flavored e-cigarette use (use 1 or more nontobacco flavors) prevalence estimates were compared across subpopulation groups using 2-sided statistical significance tests in the July 2018 Current Population Survey Tobacco Use Supplement, a nationally representative cross-sectional adult survey (n = 46 759).

resultsCurrent flavored e-cigarette use was reported by 1.6% (95% confidence interval [CI] = 1.47% to 1.69%) of all respondents. Among current vapers, the percentage of those who used flavored e-cigarettes was higher for adults aged 18-24 years (89.6%), 25-34 years (86.7%), and 35-44 years (76.0%) than for adults aged 45 years and older (60.4%, Ps < .001); was higher in never smokers (89.8%) than current (72.9%), long-term former (73.9%), and recent former (80.4%) smokers (Ps ≤ .009); was higher in smokers who reportedly did (78.9%) vs did not (71.1%) use e-cigarettes to vape where or when smoking is not allowed (P = .005); and did not differ between smokers who reportedly did (75.0%) vs did not (73.9%) vape to quit smoking (P = .71). Individuals who vaped to quit smoking and currently used flavored e-cigarettes constituted 0.9% (95% CI = 0.82% to 0.99%) of all adults (weighted N = 2 251 000, 95% CI = 2 046 000 to 2 476 000) and 57.2% of current flavored e-cigarette users.

conclusionsFlavored e-cigarette use prevalence was low among US adults overall but common for current vapers. Flavored e-cigarette use was disproportionately prevalent among never smokers and other subpopulations that might experience harm from vaping.
