Racial Disparities in Nulliparous Singleton Term Vertex Cesarean Deliveries: Rates, Reasons, and Time to Delivery.

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
backgroundNon-Hispanic Black individuals have the highest odds of having a nulliparous term singleton vertex (NTSV) cesarean birth out of all racial and ethnic groups, but this disparity is not well understood. This study assesses the factors associated with overall rates of NTSV cesarean delivery, differences in reasons for cesarean births, and door-to-delivery time among individuals who had an NTSV cesarean delivery.
methodsRetrospective analyses assessed n = 31,826 NTSV births from January 1, 2016 to December 31, 2021 at 11 medical centers in North Carolina. For each outcome variable, multivariate regression estimated Black-White disparities while controlling for clinical and social covariates. Models included random intercepts for facility and delivery provider.
resultsAfter accounting for covariates, non-Hispanic Black patients were more likely to have an NTSV cesarean delivery compared to non-Hispanic White patients (AOR = 1.48, 95% CI 1.47, 1.69). Among those who had an NTSV cesarean delivery, non-Hispanic Black patients were more likely than non-Hispanic White patients to have a cesarean delivery due to fetal intolerance of labor (AOR = 2.10, 95% CI 1.87, 2.42). Non-Hispanic Black patients had a shorter door-to-delivery time for unscheduled NTSV cesarean deliveries than non-Hispanic White patients (b = -1.80, 95% CI -2.50, -1.11).
conclusionsWe confirmed the persistence of a racial disparity in cesarean delivery rates after controlling for multiple social and clinical factors. As fetal intolerance of labor has been described as a subjective indicator, and faster door-to-delivery time for cesarean deliveries may indicate faster decision making, our findings indicate a need to better understand decision making around cesarean deliveries.
