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

backgroundMaternal mental health issues including depression are becoming increasingly critical worldwide. The risk of suicide during the postpartum period is significantly higher among individuals with depression than in those without. Although Japan has one of the lowest maternal mortality rates globally, a recent study revealed a disproportionately high number of maternal deaths due to suicide. Recent research, mainly among older adults with sarcopenia, suggests that a decrease in skeletal muscle mass is associated with the deterioration of mental health, including depression. We aimed to evaluate the association between maternal skeletal muscle mass and postpartum depressive symptoms using bioelectrical impedance analysis and the Edinburgh Postnatal Depression Scale (EPDS).

methodsThis prospective cohort study was conducted between 2022 and 2025. Pregnant East Asian women were recruited during their first trimester of pregnancy. Maternal body composition was measured four times using a multi-frequency bioelectrical impedance analyzer during the first, second, and third trimesters and 1 month postpartum. Multiple linear regression analysis was performed to assess the association between EPDS scores and the maternal skeletal muscle mass index (SMI) and ΔSMI during pregnancy and after birth. ΔSMI was defined as the change in SMI during each measurement period.

resultsOf the 318 pregnant women, 4.4% had an EPDS score of ≥ 9. The median (interquartile range) of SMI for each trimester and 1 month postpartum was 6.52 (6.16-6.92), 6.63 (6.28-7.03), 6.82 (6.45-7.35), and 6.70 (6.37-7.10), respectively. Multiple linear regression analysis did not reveal an association between EPDS scores and maternal SMI or ΔSMI.

conclusionsMaternal SMI during pregnancy and postpartum was not significantly associated with the EPDS score. Although this study does not suggest any new interventions for postpartum mental health care, many participants had a low EPDS scores which warrants further case accumulation and research in this field.
