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
objectiveThe effect of parity on labor progression following term pre-labor rupture of membranes (PROM) has been described, but detailed patterns among grand multiparous women remain unclear. Traditional labor models show accelerated labor with increasing parity, yet few studies have specifically examined PROM latency distributions or heterogeneity within high-parity groups. The aim of the present study was to characterize labor progression after term PROM across parity groups, with specific focus on identifying heterogeneity and distinct distributional patterns among grand multiparous women.
methodsThis was a retrospective cohort study including 11 219 women with singleton, cephalic pregnancies at ≥37 weeks gestation who underwent expectant management following term PROM. Women were stratified into three groups: nulliparous (n = 4347), multiparous parity 1-4 (n = 6725), and grand multiparous parity ≥5 (n = 147). The primary outcome was PROM-to-delivery interval analyzed by mean, median, and percentile distribution. Secondary outcomes included mode of delivery and second-stage duration.
resultsMean PROM-to-delivery interval decreased with increasing parity (nulliparous 13.4 ± 7.1 h vs multiparous 10.4 ± 6.3 h vs grand multiparous 10.2 ± 6.5 h; P < 0.001). While grand multiparous women had labor kinetics comparable to multiparous women at lower percentiles, a biphasic pattern emerged: beyond the 70th percentile, latency in grand multiparous women plateaued and resembled nulliparous progression. Grand multiparous women had the shortest second stage (14.3 ± 9.8 min) and highest spontaneous vaginal delivery rate (96.6%).
conclusionBeyond confirming known parity-related differences in labor duration after term PROM, this study demonstrates clinically relevant heterogeneity within the grand multiparous population. A distinct subgroup shows delayed progression that is not captured by mean or median estimates. Distributional, percentile-based assessment may refine counseling and support more individualized timing of intervention following term PROM.
