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

Depression is a global public health concern with a steadily increasing prevalence. Previous studies examining the association between interleukin-6 (IL-6) gene polymorphisms and depression have produced inconsistent findings. Therefore, we conducted a meta-analysis to clarify the association between IL-6 gene polymorphisms and susceptibility to depression. From eight eligible articles identified, seven studies providing data for the rs1800795 variant were included in the quantitative synthesis. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the genetic association under allelic, dominant, recessive, homozygous, and heterozygous genetic models. The meta-analysis revealed no significant association between the IL-6 rs1800795 polymorphism and susceptibility to depression under the allelic, dominant, recessive, homozygous, and heterozygous genetic models (G vs. C, OR = 1.05, 95%CI: 0.83–1.32, P = 0.70; GG + CG vs. CC, OR = 1.10, 95%CI: 0.69–1.75, P = 0.68; GG vs. CC + CG, OR = 1.11, 95%CI: 0.87–1.43, P = 0.40; GG vs. CC, OR = 1.24, 95%CI: 0.79–1.94, P = 0.35; CG vs. CC, OR = 1.04, 95%CI: 0.65–1.66, P = 0.87). Subgroup analyses stratified by control source and participants’ physical condition also revealed no significant associations under any genetic model. Although no direct association was found, our findings suggest that IL-6 rs1800795 does not confer categorical risk in isolation. Future research should prioritize gene-environment interactions rather than single-locus effects to clarify its role in depression pathogenesis.
