Effects of transcranial direct current stimulation (tDCS) on isometric endurance performance and electromyographic activity of the vastus lateralis in healthy male.
Article in Experimental brain research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To investigate the effects of anodal tDCS on isometric endurance peformance and sEMG activity of the vastus lateralis in healthy male with experience in resistance training. Fifteen healthy, resistance-trained males aged 18 to 35 participated in three sessions, each separated by one week. The initial session included an maximal isometric voluntary contraction (MIVC) test and familiarization with the fatigue task. In the second and third sessions, conducted randomly, participants underwent either anodal tDCS or placebo tDCS (sham). Immediately after the conditions, the subjects performed the fatigue task for right knee in the horizontal leg-press exercise, consisting of eight, lasting five seconds and having a five-second interval between contractions. The results showed no interaction between conditions and contractions in isometric endurance performance across contractions (p = 0.78) or in the sEMG activity of the vastus lateralis muscle (p = 0.94). The specific anodal tDCS protocol used in this study does not enhance isometric strength endurance or surface electromyographic activity of the vastus lateralis muscle in strength-trained men.
