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

backgroundPremature rupture of membranes (PROM) precedes 8‑10% of births and remains a leading cause of neonatal morbidity. Although infection, prior obstetric history, and cervical pathology are recognized contributors, data on the relative influence of maternal age, parity, mode of delivery, and seasonality are inconsistent across regions. Clarifying these determinants could enhance antenatal risk stratification and guide preventive counselling.

methodsWe retrospectively reviewed all singleton deliveries recorded in a tertiary care obstetric database from January 2018 through December 2020. Maternal age was grouped as <20, 20‑24, 25‑29, 30‑34, and ≥35 years; parity was dichotomized (primipara vs. multipart). The final mode of delivery (vaginal vs. cesarean) and calendar month of birth were extracted. Incidence of PROM was compared among age groups by the Kruskal-Wallis test, between parity and delivery‑mode strata by χ² tests, and across months by the Friedman test; Holm-Bonferroni corrections addressed multiple comparisons.

resultsAcross the three‑year period, PROM complicated 13.7% of deliveries. Incidence varied significantly by age (H = 19.95; p = 0.00051), peaking in women aged 25‑29 and lowest in those ≥35. Primiparas showed markedly higher PROM rates than multiparas each year (2018: 29.8% vs. 3.9%; 2019: 22.9% vs. 7.3%; 2020: 23.3% vs. 6.2%; all p < 0.0001). PROM was likewise more frequent in pregnancies that ultimately required cesarean section (17.5‑20.2%) than in vaginal births (9.3‑11.1%) during each study year (all p < 0.0001). No significant month‑to‑month or seasonal trend was detected (χ² = 0.50; p = 0.779).

conclusionsIn this temperate‑climate cohort, PROM clustered in younger, first‑pregnancy mothers and was strongly associated with subsequent cesarean delivery, while advanced maternal age and seasonality exerted minimal influence. These findings highlight nulliparous women in the 20-29-year age group as a key population for targeted education, intensified surveillance, and early labor management planning. Future prospective studies should explore the biological mechanisms underlying the age‑parity interaction and evaluate interventions, such as infection screening or cervical support, that may mitigate PROM risk in this high‑incidence group.
