1 · What the graph read from it

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.

2 · The registry

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 and Aims: The optimal timing of cesarean delivery in women with placenta previa (PP) remains controversial because earlier delivery may reduce maternal risks, whereas later delivery may improve neonatal outcomes. This study aimed to evaluate whether delaying planned cesarean section (CS) until 38 gestational weeks was associated with improved neonatal outcomes without increasing maternal risks in women with PP who remain clinically stable. Methods: This historical control study included women with singleton pregnancies complicated by PP who underwent CS at a single tertiary center between 2015 and 2024. Planned CS was scheduled at 38 Results: Of the 204 eligible women, 29 were included in Group A and 81 in Group B. Maternal outcomes, including blood loss, operation time, and rates of severe complications, were comparable between the groups. In contrast, neonatal outcomes were improved in Group A, with higher birthweight and lower rates of neonatal hospitalization and hypoglycemia. Most obstetric complications occurred before 36 gestational weeks in both periods. Conclusion: Delaying planned CS until 38 gestational weeks in clinically stable women with PP was associated with improved neonatal outcomes without an apparent increase in maternal risks or emergency CS. These findings support further investigation of the optimal timing of delivery in women with PP.
