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

objectivesInitiation of tobacco, alcohol and illicit substance use typically occurs during adolescence, with the school setting recommended to reduce adolescent substance use. Strengthening individual (eg, problem solving) and environmental (eg, caring relationships at school) resilience protective factors of adolescents has been suggested as a strategy for reducing substance use by adolescents; however, few studies have examined this potential. A study was conducted to investigate the effectiveness of a pragmatic school-based universal 'resilience' intervention in reducing the prevalence of tobacco, alcohol and illicit substance use, and increasing the individual and environmental protective factors of students.

designA cluster-randomised controlled trial.

settingThirty-two Australian secondary schools (20 intervention; 12 control).

participantsCohort of grade 7 students followed-up in grade 10 (2014; aged 15-16 years).

interventionA pragmatic intervention involving school staff selection and implementation of available programmes and resources targeting individual and environmental 'resilience' protective factors for all grade 7-10 students was implemented in schools (2012-2014). School staff were provided implementation support. MEASUREMENTS: An online survey collected baseline and follow-up data for primary outcomes: tobacco (ever, recent) and alcohol (ever, recent, 'risk') use, and secondary outcomes: marijuana and other illicit substance use, and individual (six-factor subscales, aggregate) and environmental (three-factor subscales, aggregate) protective factor scores. Generalised and linear mixed models examined follow-up differences between groups.

resultsFollow-up data from 2105 students (intervention=1261; control=844; 69% of baseline cohort) were analysed. No significant differences were found between intervention and control students for any primary (ever tobacco: OR 1.25, 95% CI 0.92 to 1.68, p=0.14; recent tobacco: OR 1.39, 95% CI 0.84 to 2.31, p=0.19; recent ever alcohol: OR 1.11, 95% CI 0.83 to 1.48, p=0.46; alcohol: OR 1.13, 95% CI 0.78 to 1.62, p=0.51; 'risk' alcohol: OR 0.98, 95% CI 0.70 to 1.36, p=0.89) or secondary outcomes (marijuana: OR 1.12, 95% CI 0.74 to 1.68, p=0.57; other illicit substance: OR 1.19, 95% CI 0.67 to 2.10, p=0.54; individual protective factors: MD=0, 95% CI -0.07 to 0.06, p=0.89; environmental protective factors: MD: -0.02, 95% CI -0.09 to 0.06, p=0.65).

conclusionsThe universally implemented pragmatic school-based intervention was not effective in reducing the prevalence of tobacco, alcohol or illicit substance use, or in increasing the protective factors of students.
