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 Khat is a green leaf with amphetamine-like effects. Khat chewing was once a socially acceptable behavior but has come to involve children and affects oral and general health. We evaluated an awareness program addressing the adverse health risks of khat chewing (AHRKC) among secondary school students, in addition to exploring the variables associated with post-intervention awareness. MATERIAL AND METHODS A quasi-experimental pre-post study design was used. A total of 450 secondary school students were recruited (intervention, n=225; control, n=225) using multistage random sampling. Self-administered questionnaires were used for data collections. For the intervention group, the khat chewing educational program included lectures and seminars, posters, billboards, and brochures. Statistical analyses included chi-squared tests, t tests, and logistic regression modelling. RESULTS A total of 427 students completed both baseline and follow-up surveys. The overall levels of exposure to anti-khat messages and awareness were significantly higher in the intervention group than in the control group after the program (P<0.001). The multivariable analysis revealed that older students (odds ratio (OR)=3.35; 95% confidence interval (CI)=1.11-10.14, P=0.031), students' monthly pocket money (OR=2.39; 95% CI=1.04-5.47, P=0.018), and frequent exposure to mass media channels (OR=2.40; 95% CI=1.06-5.46, P=0.023) were significantly associated with enhanced awareness of the AHRKC in the intervention group. CONCLUSIONS The customized educational program improved awareness of AHRKC among secondary school students. Age, pocket money, and message exposure frequency were among the factors that influenced the observed program outcomes.
