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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Stimulants such as methylphenidate (MPH) are the first-line pharmacological treatment for attention-deficit/hyperactivity disorder (ADHD). Although stimulants are effective at a group level, individual response varies, which advocates for tailored treatment approaches. Prior studies suggested that neurobiological measures following a single dose of stimulants are indicative of longer-term clinical response. To expand these findings, we tested whether an association between acute and longer-term treatment response can also be identified using measures commonly used in clinic. Sixty adults with ADHD completed clinico-neuropsychological measures, including the Barkley Adult ADHD Rating Scale-IV (BAARS-IV) and the Quantitative behavior (Qb) test, following a single dose of MPH (20 mg) and placebo. These measures were repeated after two-month MPH treatment to ascertain response. We tested associations between single-dose and longer-term response using univariate and multivariable (Lasso) regression approaches. We also ran correlations between predicted and true outcome measures. Univariate regressions showed significant associations between single-dose and two-month improvement in BAARS hyperactivity/impulsivity and Qb scores (all p < 0.001 but Qb activity, p = 0.006). Multivariable models including acute response and baseline clinicodemographic measures yielded significant correlations between predicted and actual values for all BAARS-IV and Qb scores at follow-up, except for BAARS inattention and Qb activity. Most had large/very large effect size (up to r = 0.69). These findings suggest that specific clinico-neuropsychological changes following a single dose of MPH may be indicative of longer-term treatment response, especially when combined with pre-treatment clinico-demographic characteristics. Once validated in larger and more heterogeneous samples, these results may support more informed and individualized treatment approaches for ADHD.
