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

objectiveEmerging evidence implicates neuroinflammation in the pathogenesis of major depressive disorder (MDD), yet the role of memory B cells remains unclear. In this study, we conducted a bidirectional two-sample Mendelian randomization (MR) study and Bayesian colocalization analyses to investigate the causal relationships between memory B-cell traits and MDD risk.

methodsMDD summary data were gathered from a meta-analysis of genome-wide association studies (GWASs), whereas memory B-cell genetic variations were sourced from GWASs on immune phenotypes. MR analysis utilized the inverse variance weighted (IVW), MR-Egger, and weighted median methods. Moreover, various sensitivity analyses, including Cochran's Q test, MR Pleiotropy Residual Sum and Outlier (MR-PRESSO), MR-Egger intercept test and Leave-one-out (LOO) analysis, were performed to confirm MR result stability. Bayesian colocalization analyses were also conducted to identify genetic loci shared between memory B cells and MDD.

resultsOur results indicated that genetically predicted increased CD27 protein expression on memory B cells causally elevated MDD risk (ORs: 1.025-1.063, P

conclusionsThese findings highlight CD27 as a potential novel biomarker and therapeutic target in MDD, warranting further clinical validation in the future.
