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

backgroundBright light therapy (BLT) demonstrates efficacy in alleviating subthreshold depression (StD) among young adults. The amygdala plays a critical role in depression.

methodsStD subjects were divided into BLT group (N=47) and placebo group (N=42). Depression severity was assessed using HAM-D, Centre for Epidemiologic Studies Depression Scale (CES-D) and Beck Depression Inventory (BDI) pre-/post-8-week intervention. Structural/resting-state fMRI scan was conducted. Seed-based static FC (sFC) and dynamic FC (dFC) analyses of the bilateral amygdala and their subfields were conducted.

resultsCompared to placebo, BLT showed reduced depression scale, and increased sFC of right basolateral amygdala (BLA)/superficial amygdala (SFA)-right middle temporal gyrus (MTG) and dFC of right centralmedial amygdala (CMA) and right inferior orbital frontal gyrus, and decreased sFC of right amygdalostriatal transition/CMA- left thalamus and dFC of right SFA- right medial prefrontal cortex after intervention; while the whole amygdala and its subnuclei volume did not change significantly after BLT. Right BLA-MTG sFC changes positively correlated with BDI improvement. Baseline amygdala sFC/dFC predicted post-BLT symptom changes. BLT-induced right BLA sFC alterations spatially correlated with 5-HT1A/5-HT2A receptor distributions, and right CMA dFC changes with 5-HT1A.

conclusionsFindings suggest BLT modulates amygdala-thalamocortical circuits and serotonergic pathways, highlighting FC biomarkers for treatment efficacy assessment. TRIAL REGISTRATION CLINICALTRIALS.GOV IDENTIFIER: ChiCTR2000032633.
