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

introductionConverging evidence implicates elevated inflammation in the pathophysiology of depression and its medical comorbidities. Despite known sex differences in both inflammatory activity and depression, a dedicated large-scale review of these differences is lacking.

methodsWe conducted a sex-stratified systematic review and meta-analysis of studies examining associations between depression and blood-based inflammatory markers in adult humans. Searches of PubMed, PsycINFO, and Scopus, and reference treeing, yielded 124 eligible papers including data from 423,421 participants (53% female). Analyses focused on depression and inflammatory markers C-reactive protein (CRP), interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL-1β, and fibrinogen. Sex-stratified meta-analyses and meta regressions for the effects of sex were conducted, separately for cross-sectional and longitudinal designs.

resultsCross-sectionally, depression was modestly associated with higher levels of all markers combined in both females (Cohen's d = 0.06, 95% CI [0.03-0.10]) and males (Cohen's d = 0.14, 95% CI [0.09-0.19]). Depression was associated with elevated IL-6 in females, and elevated CRP and IL-6 in males. Longitudinally, elevated IL-6 was associated with subsequent depression among females and elevated CRP was associated with depression in males, whereas depression was not associated with subsequent inflammation in either sex.

conclusionOverall, results indicated modest associations between depression and elevated inflammation in both sexes, with slightly stronger associations in males. Associations between specific inflammatory markers (i.e., IL-6 in females and CRP in males) and subsequent depression differed by sex. These findings highlight the cross-sex relevance of inflammation in depression, and subtle sex differences in directionality and specific markers.
