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
Background: Racial and ethnic disparities exist in the rates of and indication for cesarean delivery, prompting the implementation of quality initiatives designed to target the drivers of these inequities. Few studies have assessed the impact of these initiatives on reducing these disparities. Objectives: To determine the rates of and indications for cesarean delivery before and after the implementation of perinatal quality improvement (QI) initiatives. Study design: Retrospective cohort study of 3629 nulliparous individuals with full-term live-born, singleton gestations in vertex position (NTSV) who delivered at a large academic tertiary care center in the United States from October 2019 through December 2022. Perinatal QI initiatives, designed to promote vaginal birth and improve equity in birth outcomes, were implemented during this period. This included the Promoting Vaginal Birth (PVB) initiative implemented in October 2020, followed by the Birth Equity (BE) initiative in May 2021. An interrupted time series analysis was performed to examine the relationship between the implementation of perinatal QI initiatives and trends in cesarean delivery rates. Distributions of demographic, clinical, and structural characteristics were examined by indication for cesarean and race and ethnicity. Multivariable multinomial logistic regression models assessed the independent association between race and ethnicity and indication for cesarean delivery after adjusting for maternal, perinatal, and system-level risk factors before and after implementation of perinatal quality initiatives. Results: The rate of NTSV deliveries increased immediately following the start of quarter I (step-change Conclusions: Quality initiatives to promote vaginal birth and birth equity may reduce the overall rate of NTSV cesarean delivery. However, additional efforts are necessary to understand and mitigate disparities in indication for cesarean delivery among minority pregnant individuals.
