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

purposeTo examine the effects of single-dose anodal tDCS on isometric maximal voluntary contraction (MVC) and isometric endurance performance in lower limb exercises with healthy adults.

methodsFor this systematic review and meta-analysis, we searched PubMed, ISI Web of Science, Scopus, and CINAHL for studies published between database inception and June 11, 2024. All randomized controlled trials on anodal tDCS interventions for MVC and isometric endurance in lower limb exercises were included, with no date restrictions. The quality of the evidence was assessed using the Jadad Scale, and the certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach. The Open Science Framework registered the protocol in June 2024 (DOI https://doi.org/10.17605/OSF.IO/AG93M ).

results20 interventions were included, comprising 15 for MVC and 5 for 'Time to Task Failure' (TTF), which refers to isometric endurance performance measured in seconds. The findings showed no difference in the MVC (SMD = 0.06; 95% CI = - 0.14, 0.25; P = 0.57) and TTF performance (WMD = 0.07; 95% CI = - 0.26, 0.40; P = 0.68).

conclusionThe current meta-analysis indicated that anodal tDCS did not increase isometric MVC and isometric endurance performance in lower limb exercises in healthy adults.
