Development and Validation of a Prediction Model for Cardiovascular Risk in Reproductive-Aged Women.

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
backgroundCurrently available risk scores for cardiovascular disease (CVD) were developed in older populations and do not incorporate sex-specific factors, which limits their ability to provide accurate estimates in younger women.
objectivesThe objective of the study was to develop and validate a prognostic model, including female-specific risk factors, that can identify women at high risk.
methodsWe created a cohort of 262,891 women aged 15 to 45 years with 1 randomly selected delivery from 1999 to 2017 in the Clinical Practice Research Datalink database to develop models for screening women within the first-year postpartum. The primary outcome was incident CVD. The least absolute shrinkage and selection operator method and an accelerated failure time Weibull model were used to determine the inclusion of predictors and to estimate the final model. Internal validation via bootstrapping was used to estimate the optimism-corrected measures of model performance.
resultsA total of 943 women (0.81 per 1,000 person-years) experienced a cardiovascular event over a median follow-up of 3.8 years (Q1-Q3 1.5-7.9). Predictors in the final model included traditional CVD risk factors, along with social deprivation, polycystic ovary syndrome, prior use of oral contraceptives, depression, thyroid disorders, hypertensive disorders of pregnancy, gestational diabetes, preterm birth, small-for-gestational-age birthweight, parity, and history of pregnancy complications. Optimism-corrected performance median (Q1-Q3) measures showed modest discrimination (C-statistic: 0.637 [0.623-0.650]) and good calibration (slope: 0.919 [0.905-0.930]).
conclusionsAlthough the model showed modest predictive accuracy and performance, the findings highlight the importance of sex-specific risk factors for identifying women at high risk of CVD in the postpartum period.
