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

Excessive attention bias interferes with daily life and contributes to various psychiatric conditions. Previous studies have demonstrated that anodal transcranial direct current stimulation (tDCS) applied to the left dorsolateral prefrontal cortex (DLPFC) can enhance attentional control and reduce negative emotional bias. However, little is known about the effects of transcranial random noise stimulation (tRNS) on attention bias. This study aimed to investigate whether tRNS reduces attention bias toward negative emotional stimuli compared to tDCS, for which functional evidence has been established. This randomized, double-blind, crossover, sham-controlled study enrolled 32 healthy right-handed men. The emotional Stroop task was used to assess attention bias. The participants experienced all three stimulation conditions: tRNS, tDCS, or sham, with each condition separated by a 7-day washout interval and administered in a random order. tRNS to the left DLPFC significantly reduced attention bias toward negative stimuli compared with sham (corrected p = 0.047, Cohen’s d = 0.72), whereas no significant difference was observed between tRNS and tDCS. Positive correlations were observed between the effects of each stimulation condition and attention bias in the sham condition in the tRNS and tDCS groups; however, these associations did not exceed the empirical null distribution determined by permutation testing. Thus, the modulatory effects of tRNS on attentional control may not strictly depend on baseline bias magnitude, suggesting its potential applicability in both healthy and clinical populations characterized by excessive attention bias.
