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

backgroundAlthough it is widely recognized that insulin resistance (IR) plays a critical role in the development of erectile dysfunction (ED), the specific relationship between IR and ED among non-diabetics has been little studied, and no relevant large-scale studies have been conducted. The purpose of this study is to examine the association between different IR surrogates and the risk of ED in non-diabetic populations.

methodsNational Health and Nutrition Examination Survey (NHANES) 2001-2004 data were used for this cross-sectional analysis. Weighted multivariable logistic regression and restricted cubic spline curves (RCS) were performed to evaluate the relationship between homeostasis model assessment (HOMA-IR), triglyceride glucose (TyG), TyG with body mass index (TyG-BMI), TyG with waist circumference (TyG-WC) and TyG with waist-to-height ratio (TyG-WHtR), and ED risk. When segmenting effects were detected, recursive algorithms were used to determine potential inflection points. Then log-likelihood ratio test and weighted segmented regression were carried out. In the sensitivity analysis, stratified and interaction analyses were performed.

resultsA total of 1569 (weighted: 76450963) individuals eventually were enrolled in the study. After adjusting for all confounders, the TyG did not correlate with ED (P > 0.05), whereas the other IR surrogates, HOMA-IR, TyG-BMI, TyG-WC, and TyG-WHtR, remained positively correlated with ED [ORs (95% CIs) were 1.02 (0.95, 1.10), 1.01 (1.00, 1.02), 1.00 (1.00, 1.01), 1.17 (0.84, 1.63), respectively; all P < 0.05]. Furthermore, we found the risk of ED was significantly higher when TyG-BMI > 328.94 or TyG-WC > 1128.25 or TyG-WHtR > 6.42 [the ORs (95% CIs) were 1.05 (1.02, 1.08), 1.02 (1.01, 1.03) and 51.30 (4.46, 453.64), respectively]. No interactions were found between these IR surrogates and the stratification variables.

conclusionsIn the non-diabetic population, ED risk was positively associated with elevated HOMA-IR, TyG-BMI, TyG-WC, and TyG-WHtR.
