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

backgroundAntenatal breast milk expression (ABME) is a potential strategy to promote breastfeeding, but its clinical safety and efficacy remain unclear.

objectiveThe study aims to systematically evaluate the impact of ABME on breastfeeding, maternal, and neonatal outcomes.

methodsEleven electronic databases were searched from inception to January 14, 2026, to identify randomized controlled trials (RCTs) investigating ABME. Study quality was assessed using the Cochrane Risk of Bias tool. Heterogeneity was evaluated using the I

resultsA total of 3,077 studies were identified. After the removal of duplicates and selection, eleven RCTs studies involving 1,571 women met the inclusion criteria and eight studies were included in the meta-analysis. Compared to the standard care group, women who performed ABME have a lower risk of DOL II in the postpartum period (odds ratio [OR]: 0.30; 95% CI: 0.16-0.56; I

conclusionABME effectively reduces the incidence of DOL II and supports early exclusive breastfeeding without compromising maternal or neonatal safety.
