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

Purpose: We aimed to assess the association between postpartum weight retention (PPWR) in the 4th-week post-delivery and the risk of large-for-gestational-age (LGA) infants in the second pregnancy. Methods: This nationwide prospective birth cohort analysis included 3137 women who delivered their first two live singletons between 2011 and 2014. The PPWR was defined as the body mass index (BMI) after 4 weeks of the first birth minus the pre-pregnancy BMI of the first pregnancy. LGA infants were compared among four PPWR groups: less than - 1 (a BMI loss of > 1 unit), - 1 to < 1 (the reference: stable PPWR group), 1 to < 3 (a BMI gain of 1-3 unit) and ≥ 3 (a BMI gain of > 3 unit). PPWR was assessed not only in all women but also in women with a BMI < 25 and ≥ 25 kg/m Results: The incidence of LGA infants was 8.8% (277 out of 3137). After adjusting for potential confounding factors, no association was observed between the risk of an LGA infant in the second pregnancy and the PPWR in all eligible women. Similarly, no association was observed between LGA risk in the second pregnancy and thePPWR in the pre-pregnancy BMI < 25 kg/m Conclusion: PPWR measured in the 4th-week post-delivery was not associated with an increased risk of LGA infants in the second pregnancy. Supplementary Information: The online version contains supplementary material available at 10.1007/s40200-025-01749-8.
