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

aimGiven the significant decline in exclusive breastfeeding rates in the Republic of Korea, this study aimed to estimate the causal effect of immediate skin-to-skin contact on exclusive breastfeeding.

methodsData were analysed from the Korean Early Childhood Education & Care Panel, targeting mothers expected to give birth in 2022 in the Republic of Korea. Instrumental variable analysis was performed using the mode of delivery, categorised as vaginal delivery and emergency caesarean section, as the instrument. Statistical estimation was performed using the two-stage least squares method.

resultsMothers who engaged in immediate skin-to-skin contact were 36.3% more likely to exclusively breastfeed at 1 month postpartum, and 26.9% and 26.2% more likely at 2 and 3 months, respectively, compared to those who did not. Sensitivity analysis confirmed the robustness of these findings. Notably, the effect of immediate skin-to-skin contact on exclusive breastfeeding at 1 month remained statistically significant, despite considerable deviations from the exclusion restriction assumption.

conclusionImmediate skin-to-skin contact positively influences exclusive breastfeeding rates up to 3 months postpartum. These findings are particularly relevant for healthcare settings where immediate SSC is not routine, highlighting the importance of targeted training and policy interventions to promote SSC and improve breastfeeding outcomes.
