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.

Abstract

Opp is a universal mental health-promoting mobile application (app) developed for adolescents, with the aim of promoting mental health and well-being and preventing mental health problems. In this randomized controlled trial, the effectiveness of Opp was tested among Norwegian adolescents aged 13 to 25 years. Mental health, well-being, self-efficacy, self-esteem, help-seeking behavior, and sleep quality were assessed at two measurement points (T1 and T2), that were approximately 11 weeks apart. Only the participants that answered at both measurement points were included in the main analyses (
