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

Obesity significantly contributes to declining serum testosterone levels in men, with chronic inflammation being a crucial potential mechanism; Clinical research evidence directly supporting this pathway remains limited. We investigated how obesity relates to serum testosterone in males, with particular attention to the intermediary role of chronic inflammation. Our study included adult males aged ≥20 years from the National Health and Nutrition Examination Surveys (NHANES) conducted from 2011 to 2016 and from 2021 to 2023. Obesity status was assessed with body mass index (BMI), body roundness index (BRI), and waist circumference (WC). Chronic inflammatory status was assessed with an aggregate index of systemic inflammation (AISI), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI). Multivariable regression assessed associations between obesity metrics and testosterone. The indirect influence of inflammatory indicators was assessed through mediation analysis. Subgroup analyses were performed by weight status. The study comprised 7,418 participants. Multivariable linear regression revealed that obesity (BMI, WC, BRI) was negatively associated with male serum testosterone. Generalized additive models indicated a nonlinear relationship, showing a clear inverse association. Chronic inflammatory status (SII, SIRI, and AISI) mediated the association between obesity and male serum testosterone. In subgroup analyses, the association was consistent with overall findings, but the mediating effect of chronic inflammatory status was statistically significant only in the group with obesity (BRI ≥4.5, WC ≥102 cm, and BMI ≥30 kg/m
