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

This double-blind, sham-controlled randomized clinical trial investigated whether a single session of anodal-(a) transcranial direct current stimulation (tDCS), applied over the primary motor cortex (M1), cerebellum (CB), or both, would reduce pain and increase corticospinal excitability more effectively than sham stimulation (s-tDCS). Ninety-two women with fibromyalgia were randomized to a single session of anodal-(a)-tDCS or sham-(s)-tDCS. Primary outcomes were pain intensity, assessed with the Numerical Pain Scale (NPS), and corticospinal excitability, measured by motor evoked potentials (MEP). Compared to sham, a-tDCS significantly reduced NPS scores (Wald χ
