Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Adult Laboratory Classroom Study of the Efficacy and Safety of PRC-063 (Extended-Release Methylphenidate) for the Treatment of ADHD.
Trial report in Journal of attention disorders, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03618030 (A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Parallel Group, Adult Laboratory Classroom Study to Evaluate the Safety and Efficacy of PRC-063 Compared to Placebo in Adults With ADHD), which is not on this map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
objectiveTo evaluate the efficacy, safety, and duration of action of the once-daily extended-release methylphenidate formulation PRC-063 for the treatment of ADHD in an adult laboratory classroom (ALC).
methodAfter dose optimization with PRC-063 over 7 weeks, adults with ADHD were randomized to 1 week of double-blind treatment with PRC-063 or placebo that ended with an ALC evaluation. The primary outcome measure was Permanent Product Measure of Performance-Total (PERMP-T) score.
resultsOf 288 subjects enrolled, 221 completed the ALC visit. PERMP-T score was significantly higher for PRC-063 versus placebo at every assessment from 1 to 16 hours post-dose at the ALC visit and when averaged over 16 hours post-dose (least-squares mean difference 16.3, 95% confidence interval 7.6-24.9). The most frequent adverse events during dose optimization were headache, decreased appetite, and insomnia.
conclusionPRC-063 provided rapid and sustained symptom relief in adults with ADHD and was well tolerated. NCT03618030.
