High Philadelphia Adverse Childhood Experiences Survey Score Is Associated With Spontaneous Preterm Birth Among Black Pregnant Individuals: A Secondary Analysis of a Prospective Cohort.
Observational study in BJOG : an international journal of obstetrics and gynaecology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo assess associations between two surveys of adverse childhood experiences (ACEs)-Kaiser ACE and Philadelphia ACE-and spontaneous preterm birth (sPTB) among Black individuals.
designSecondary analysis of a prospective observational cohort.
settingTertiary academic medical center. POPULATION OR SAMPLE: Black pregnant persons who completed both Kaiser and Philadelphia ACE surveys with adjudicated birth outcomes.
methodsWe used Chi-square analyses to measure bivariate associations between high ACE scores for both surveys (threshold ≥ 4) and sPTB. Multivariable logistic regression estimated odds ratios for sPTB comparing high vs. low Kaiser ACE score and Philadelphia ACE score, controlling for maternal education and insurance. We compared proportions of individuals who endorsed single adversities across surveys using McNemar's test (p-value < 0.05 for statistical significance).
main outcome measuressPTB (< 37 weeks' gestation).
resultsAmong 350 participants, 5.4% experienced sPTB. Among the same 350 participants, 40.8% reported a high Philadelphia ACE score and 20.9% reported a high Kaiser ACE score. In bivariate analysis, a high Philadelphia ACE score but not a high Kaiser ACE score was associated with sPTB. After adjustment, those with a high Philadelphia ACE score had 3.7 times (95% CI 1.41, 10.99) higher odds of sPTB compared to those with low scores. Comparing the conventional ACEs measured in both instruments, a higher proportion of individuals endorsed subscales of adversities on the Philadelphia ACE survey compared to the Kaiser ACE survey.
conclusionsA high Philadelphia ACE score was associated with increased sPTB. The Philadelphia ACE survey may capture childhood adversity more comprehensively than the conventional Kaiser ACE survey and thus more accurately reflect the impact of early lived experiences on adverse pregnancy outcomes, such as PTB, in Black, urban populations.
