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

backgroundThis study examined the relationship between smoke-free home (SFH) rules and susceptibility to cigarette and e-cigarette (EC) use in never-smoking adolescents in Hong Kong, focusing on the mediating role of tobacco-related attitudes.

methodsThe sample included 5,902 secondary school students (grades 7-12; 51.9% male; mean age 14.6) from a territory-wide survey in Hong Kong. Generalised linear mixed models were used to estimate the association between SFH rules and tobacco susceptibility, and structural equation models (SEM) were used to explore the mediating effect of attitudes. All tests were two-tailed with a significance level of α = 0.05.

resultsTwenty-five point two percent of participants were living with smokers, of whom 27.3% had no SFH rules, 29.5% had rules with violations, and 43.1% had rules without violations. Students from smoking families had higher prevalence of smoking susceptibility and secondhand smoke exposure, with the highest levels observed among those without SFH rules. Having SFH rules without violations was negatively associated with susceptibility to both cigarette (adjusted Odds Ratio(aOR) = 0.51, 95%CI:0.31, 0.84; AME=-0.036, 95%CI: -0.066, -0.006) and EC use (aOR = 0.63, 95%CI:0.41-0.98; AME=-0.034, 95%CI: -0.068, -0.0001) after adjusting for covariates. SEM results showed that SFH rules with violations were associated with lower cigarette susceptibility both directly (β=-0.280) and indirectly through attitudes (β

conclusionsSFH rules, especially strict rules without violations, were associated with lower susceptibility to cigarette or EC use, and this association was partly mediated through less tolerant attitudes toward tobacco use. Further research on policies and interventions on SFH rules and practice is warranted for effective tobacco prevention.
