Disparities in Patterns of Preterm and Early Term Second Births Among Non-Hispanic Black and White Mothers.

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
backgroundEarly term births (37-38 weeks), like preterm births (< 37 weeks) are associated with increased infant morbidity, mortality, and risk of future preterm births. While racial disparities in preterm births are well documented, longitudinal patterns of early term and preterm births by maternal race remain underexplored.
objectivesTo estimate the likelihood of second births that are preterm or early term, conditional on the gestational age category of the mother's first birth and maternal race.
methodsThis population-based cohort study used linked birth and hospital discharge records for non-Hispanic (NH) Black and White mothers in Georgia with a first and second singleton live birth between 2011 and 2020. We examined the unadjusted distributions of second birth gestational age (< 32, 32-36, 37-38, ≥ 39 weeks) stratified by first birth gestational age category and maternal race. Adjusted relative risk ratios (RRRs) were estimated using multinomial logit models.
resultsNH Black mothers delivered 31,768 births; NH White mothers delivered 58,113. Among mothers with a first preterm birth < 32 weeks, NH Black mothers had a higher likelihood of second births at < 32 (RRR 19.08, 95% CI 14.48, 24.98) than NH White mothers (10.17, 95% CI 7.00, 14.78) and had similar disparities for second births at 32-36 weeks. After early term first births, NH Black mothers had elevated risks of < 32 or 32-36 week births (RRRs 3.53, 95% CI 2.90, 4.30 and 2.88, 95% CI 2.64, 3.13 respectively) versus NH White mothers (1.73, 95% CI 1.41, 2.11 and 2.07, 95% CI 1.92, 2.22). Racial disparities extended to second births following full-term first births and persisted after restricting the sample to non-indicated first births.
conclusionsNH Black mothers face relatively elevated risks of shortened gestation in subsequent births, regardless of the gestational age of their first birth, including after early term or full-term births.
