Associations of four insulin resistance indicators with subsequent pregnancy outcomes in women with recurrent pregnancy loss.

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
Aims: This study investigated the associations of four insulin resistance (IR) indicators-the triglyceride-glucose (TyG) index, the TyG-body mass index (TyG-BMI), the metabolic score for IR (METS-IR), and the triglyceride to high-density lipoprotein cholesterol (TG/HDL-C) ratio-with subsequent pregnancy outcomes in women with recurrent pregnancy loss (RPL) and assessed their predictive value. Methods: This cohort study recruited RPL participants from the Chinese Pregnancy Loss Cohort. Enrollment occurred between September 2019 and December 2022. All participants were followed up every 6 months, with a minimum follow-up duration of 18 months, to document pregnancy outcomes (live birth or subsequent pregnancy loss). Univariate and multivariate logistic regression analyses were performed to assess the associations between four IR indicators (TG/HDL-C, TyG, TyG-BMI, METS-IR) and pregnancy outcomes. Receiver operating characteristic (ROC) analysis was conducted to determine the predictive efficacy of each indicator. Results: Among 2,454 screened participants, 897 RPL women were analyzed (638 live births, 71.1%; 259 pregnancy losses, 28.9%). In the fully adjusted model, the highest tertiles of TyG-BMI and METS-IR were associated with significantly elevated odds of pregnancy loss (OR = 1.52, 95% CI: 1.01-2.27, Conclusions: Among women with RPL, TyG-BMI and METS-IR are independently associated with increased pregnancy loss risk, with METS-IR demonstrating superior predictive performance.
