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

backgroundPsychotherapy for adults with ADHD is still underutilized in Germany and worldwide. Only a small percentage of these patients receive psychotherapy as recommended in the guidelines. Unguided digital interventions may help to lessen this treatment gap.

methodsAn open-label, exploratory randomized controlled trial was conducted (trial registration: DRKS00033320). Adults with confirmed ADHD were recruited at six study centers in Germany, as well as via social media, and were randomly allotted to receive either the intervention (treatment as usual + app) or the control condition (treatment as usual). Data were collected from 2 February to 5 June 2024. The primary endpoint was patients' health-related quality of life (QOL) at 12 weeks. The secondary endpoints included changes in the severity of ADHD symptoms, functional impairment, and symptoms of anxiety or depression. The threshold for statistical significance was set at 10% in view of the exploratory nature of the trial.

results307 subjects were randomized (intervention group: n = 155, control group: 152). 70% were women, 29% men, and 1% was gender diverse; their mean age was 36 years (SD, 9.5). The data were analyzed according to the intention-to-treat principle with a mixed-effects model. The improvement in QOL was greater in the intervention group than in the control group (

conclusionLimitations include that no standardized diagnostics were conducted within the study and that no conclusions can be drawn regarding long-term effects.
