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

purposeTo identify factors associated with mother-to-infant bonding difficulties (MIBD) in mothers without prior postnatal depression and to elucidate the prevalence.

methodsA total of 64,938 mother-child pairs who had registered between 2011 and 2014 in a nationwide birth cohort study called the Japan Environment and Children's Study (JECS) were analysed. MIBD was assessed using the Mother-to-Infant Bonding Scale Japanese version (MIBS-J). Prior postnatal depression was defined as an Edinburgh Postnatal Depression Scale score ≥ 9 at both 1 month and 6 months postpartum, and mothers who met this criterion were excluded. Mothers with a MIBS-J score ≥ 5 were considered to have MIBD. Cut-offs of ≥ 3 were set for MIBS-J subscale scores for lack of affection (LA)and anger/rejection (AR). We set 30 factors as exposures, and data were subjected to logistic regression analysis.

resultsThe prevalence of MIBD, LA, and AR among those without prior postpartum depression was 7.7%, 3.9%, and 11.7%, respectively. The most strongly associated factors were 'feeling difficulty in holding the baby when they were cranky or arching their back' (AOR: 3.45 [2.96-4.03]) and 'negative feelings towards the pregnancy' (AOR: 2.42 [2.20-2.65]). 'High social support' (AOR: 0.45 [0.41-0.49]) was strongly associated with the absence of MIBD without prior postnatal depression.

conclusionsIn this study, the prevalence of MIBD among women without prior postnatal depression was 7.7%. MIBD without prior postnatal depression was strongly associated with 'difficulty holding the baby when they were cranky or arching their back', 'low social support', and 'negative feelings towards the pregnancy'.
