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

introductionFundal pressure during the second stage of labor is widely practiced but understudied. Violent fundal pressure can cause maternal and fetal injuries. Many providers believe the maneuver is effective. Administrative efforts to ban fundal pressure are unsuccessful and only drive the procedure to an underground practice. MATERIAL AND

methodsIn this single-center, open-label, randomized trial, nulliparous women with term singleton cephalic pregnancy under epidural analgesia were assigned to receive gentle manual fundal pressure (GMFP) or routine labor care. The GMFP was designed not to exceed a maximum of 120 mmHg. Women were randomized after 30 min of pushing in the second stage of labor. The primary outcome was the time from randomization to delivery. Secondary outcomes were mode of delivery, episiotomy, perineal laceration, cord blood pH, and other maternal and fetal outcomes.

resultsBetween July 2023 and January 2024, 164 women were randomized to GMFP (n = 82) or to routine care (n = 82). The time from randomization to vaginal delivery did not show statistical significance between the fundal pressure group and the control group (mean [SD], 46.3 [33.3] vs. 55.9 [45.8] min; p = 0.13). Significantly fewer women in the fundal pressure group had operative vaginal deliveries (4 of 82 [4.9%]) than women in the control group (13 of 82 [15.9%]; relative risk [RR] 0.308, 95% confidence interval [CI] 0.105-0.904; p = 0.021). Similarly, mediolateral episiotomy was performed in fewer women in the fundal pressure group (6 of 82 [7.32%]) than in the control group (16 of 82 [19.51%], RR 0.375, 95% CI 0.154-0.910; p = 0.022). Other maternal and fetal outcomes were similar in the two groups.

conclusionsGMFP resulted in a nonsignificant reduction in the second stage of labor and a significant reduction in operative vaginal delivery and episiotomy without an increase in adverse outcomes. Fundal pressure during the second stage of labor deserves further investigation.
