The Acute Effect of Methylphenidate Ingestion in a Visuomotor Task at Absolute Power Alpha in Healthy Subjects.

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
Methylphenidate (MPH) is a psychostimulant widely used to enhance attention and executive functions through increased dopaminergic and noradrenergic transmission. Although its effects on cognitive performance are well documented, its acute influence on cortical oscillatory activity, particularly α power, during tasks requiring simultaneous motor and cognitive processing remains poorly understood in healthy adults.To investigate the acute effects of 10 mg MPH on absolute α power (8-12 Hz) in frontal regions during a visuomotor task in healthy subjects.A total of 13 right-handed healthy adults (7 men; age 25.6 ± 4.5 years) participated in a randomized, double-blind, placebo-controlled, crossover study. A 20-channel electroencephalography (EEG) was recorded before and after execution of the MIRA visuomotor task (joystick response when a moving target crosses a previously memorized position) under placebo and MPH (10 mg) conditions, with sessions 1 week apart. Absolute α power was compared using two-way ANOVA (condition vs. moment: pre- vs. post-joystick press), followed by paired
