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

objectiveTo present, organize, and assess the methodological quality of the current research related to tDCS on motor function after a stroke and to identify gaps and clinical implications using an evidence mapping approach.

methodsSix electronic databases (PubMed, Embase, Cochrane Library, Web of Science, CINAHL, PEDro), gray literature, and reference lists of articles were searched from inception until October 2023. The Assessment of Multiple Systematic Reviews 2 (AMSTAR-2) checklist and PEDro scale were used to assess the methodology quality of systematic reviews (SRs) and randomized controlled trials (RCTs).

resultsA total of 172 articles met the inclusion criteria from 5759 records, including 46 SRs and 126 RCTs. Related studies came from 29 countries around the world, and China has performed the most, with 12 SRs and 21 RCTs. More than half of SRs (65.22%) were evaluated with low or critically low quality, while 78.58% of RCTs have shown excellent or good quality. A total of 26 SRs and 93 RCTs have reported outcomes on upper limb motor function with kinds of tDCS, and 15 SRs and 44 RCTs have focused on lower extremity function. Studies with safety concerns have reported no or mild adverse events.

conclusionsThis study systematically identified gaps and indicated that tDCS is a kind of potential and safe intervention. Given potential concerns on the clinical application, more high-quality research with large sample size and kinds of objectives is needed in the future.
