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

backgroundNumerous studies have been conducted regarding maternal bonding; however, there is a lack of studies investigating the association with unintended pregnancy. This study aimed to examine the effects of unintended pregnancy on maternal bonding using a longitudinal design from pregnancy to one month postpartum.

methodsParticipants were 78 mothers who attended the Department of Obstetrics for prenatal care at 20.5 weeks of gestational age. They responded to the Postpartum Bonding Questionnaire (PBQ) and the Edinburgh Postnatal Depression Scale (EPDS). Furthermore, we asked whether the pregnancy was unintended. At one month postpartum, they responded to the questionnaires again. We performed two-way repeated-measures analysis of variance to assess the effect of group (unintended pregnancy or intended pregnancy) and time (during pregnancy or one month postpartum) on the PBQ and EPDS scores.

resultsMothers who had unintended pregnancies had significantly impaired maternal bonding compared to expected pregnancy mothers, both during pregnancy and one month postpartum. In addition, both unintended and expected pregnancy mothers had significantly decreased impaired maternal bonding at one month postpartum. Regarding depression, mothers with unintended pregnancy had significantly higher EPDS scores than mothers with expected pregnancy, both during pregnancy and one month postpartum.

conclusionsOur findings emphasize that healthcare providers should promptly identify mothers with unintended pregnancies and conduct thorough assessments of mother-infant interactions postpartum.
