Association between cardiometabolic index and infertility risk: a cross-sectional analysis of NHANES data (2013-2018).
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundThe cardiometabolic index (CMI), a novel measure of obesity that integrates lipid profiles and indicators of abdominal adiposity, has emerged as a promising marker of metabolic health. However, its relationship with infertility remains largely unexplored. Using data from the National Health and Nutrition Examination Survey (NHANES) conducted between 2013 and 2018, this study investigated the potential association between CMI and infertility risk.
methodsWe utilized weighted multivariate logistic regression to examine the association between CMI and infertility and employed a restricted cubic spline model to explore potential non-linear relationships. Interaction tests and subgroups analyses were conducted to assess heterogeneity across different subgroups.
resultsThe analysis included a nationally representative cohort of 1,142 women. After controlling for potential confounders, a positive association was identified between CMI and infertility risk (OR: 1.47; 95% CI: 1.05-2.06; p = 0.028). The restricted cubic spline model revealed a non-linear relationship (p = 0.0109), with an inflection point at a CMI value of 0.341.
conclusionsOur findings provides evidence of a positive association between CMI and infertility risk among U.S. adults. These results suggest that CMI could serve as a simple and effective surrogate marker for infertility risk assessment, offering valuable insights for reproductive health management.
