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

backgroundThis study aimed to evaluate maternal and neonatal outcomes following immediate delivery or expectant management of preterm premature rupture of membranes (PPROM) during the late preterm period at 34⁺⁰-36⁺⁶ weeks of gestation.

methodsWe conducted a retrospective study of singleton pregnancies with PPROM during the late preterm period using medical records from 12 tertiary medical centers in the republic of Korea between January 2007 and December 2016. Demographic characteristics and outcome measures were also recorded. The primary outcomes were maternal sepsis, neonatal sepsis, and neonatal death for neonatal outcomes.

resultsAmong 1,072 women with late PPROM, 782 (72.9%) underwent immediate delivery and 290 (27.1%) received expectant management. The incidence of clinical neonatal sepsis was significantly lower in the immediate delivery group than in the expectant management group (3.8% vs. 15.8%,

conclusionIn women with late PPROM, expectant management does not increase the risk of severe maternal or neonatal morbidity or mortality compared to immediate delivery. Therefore, with close surveillance for complications, such as chorioamnionitis and fetal compromise, particularly clinical neonatal sepsis, expectant management can be a judicious treatment option in clinical practice.
