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

aimThis phase 3, multicenter, open-label study aimed to evaluate the efficacy and safety of SDT-001, a dual-task digital device, compared to standard treatment (environmental and/or psychosocial treatment: treatment as usual; TAU) in the comparison part and to evaluate the safety, tolerability, and long-term efficacy of SDT-001 in the repetition part in Japanese children and adolescents with attention-deficit/hyperactivity disorder (ADHD).

methodsIn the comparison part, participants on standard treatment were randomized (2:1) to SDT-001 (n = 109; 25 min/day for 6 weeks, with a 4-week follow-up) or TAU (n = 55) groups. Participants (n = 126) from the comparison part transitioned to a single-arm repetition part with SDT-001 (6 weeks and followed for 12 weeks). Primary endpoint in the comparison part was changed from baseline to 6 weeks in ADHD rating scale IV (ADHD-RS-IV) inattention scores.

resultsIn the comparison part, SDT-001 demonstrated superiority to TAU, with significantly greater improvements from baseline to week 6 in ADHD-RS-IV inattention (adjusted mean difference [95% confidence interval], -2.97 [-4.38, -1.56]; P < 0.0001), total (-4.56 [-6.75, -2.38]; P < 0.0001), and hyperactivity-impulsivity (-1.55 [-2.64, -0.46]; P = 0.0056) scores. Additionally, other secondary endpoints showed improvements in symptoms in the SDT-001 group. In the repetition part, SDT-001 showed sustained reductions in ADHD-RS-IV scores till 12 weeks after completion of the 6-week treatment. No new severe adverse events or safety concerns were reported.

conclusionSDT-001 demonstrated superior efficacy at week 6 in ADHD-RS-IV compared to TAU, and reductions in scores were maintained up to the following 12 weeks, indicating its potential as a novel digital therapeutic option for ADHD management.
