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

introductionPolycystic ovary syndrome (PCOS) is a common endocrine disorder in reproductive-aged women, often accompanied by insulin resistance (IR). The contribution of cytokines in the endometrial microenvironment to IR remains unclear. This study investigated their association in PCOS to identify potential clinical targets.

methodsA case-control study involving 92 PCOS patients and 80 control subjects was conducted. Diagnosis followed the Rotterdam criteria. Insulin resistance was assessed by homeostasis model assessment of insulin resistance (HOMA-IR). Cytokines including TNF-α, IL-1β, IL-6, IL-8, IL-10, and MCP-1 in serum and uterine fluid samples were measured via enzyme-linked immunosorbent assay (ELISA). Logistic and linear regression models were utilized to evaluate associations between cytokine expression and insulin resistance.

resultsCompared with controls, PCOS patients showed higher FINS, TG, LDL, testosterone, AMH, HOMA-IR, LH, and BMI, and lower HDL (all P < 0.05). Serum and uterine fluid levels of IL-6, MCP-1, and TNF-α were significantly elevated in PCOS, while IL-8 showed no difference. Correlation analysis revealed that IL-6, MCP-1, and TNF-α were positively associated with HOMA-IR (all P < 0.05. Notably, logistic regression identified uterine fluid TNF-α as an independent predictor of insulin resistance (multivariate OR = 1.562, 95% CI: 1.151–2.122, P = 0.004). ROC analysis showed that uterine fluid TNF-α effectively predicted insulin resistance in PCOS (AUC = 0.81), outperforming IL-6 and MCP-1.

conclusionsElevated uterine TNF-α in PCOS is closely linked to insulin resistance, highlighting the role of local inflammation in disease pathophysiology. Targeting TNF-α may offer a promising strategy to improve both metabolic and reproductive outcomes.
