Trial reportBMC pregnancy and childbirth2025
Randomized controlled trial investigating the effect of a childbirth and parenting booklet intervention on paternal postpartum depression risk.
Trial report in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundPaternal postpartum depression (PPPD) remains underrecognized globally, despite prevalence estimates comparable to maternal depression. This study investigated whether a childbirth and parenting booklet distributed to expectant fathers during the prenatal period could reduce the risk of PPPD.
methodsWe performed a parallel-group, randomized controlled trial conducted in an obstetrics clinic in Japan. We recruited expecting fathers and their pregnant partners at 28-32 weeks gestation. In total, the intervention and control groups comprised 236 and 234 couples, respectively. The intervention comprised of a childbirth and parenting booklet that was distributed to the fathers by postal mail at 32 to 34 weeks gestation. The primary outcome was the incidence of paternal depression at 1 or 3 months after delivery. The secondary outcomes measured in this study included various indicators related to participants and childcare.
resultsAt follow-up, signs of depression were observed in 7.2% of fathers in the intervention group and 9.8% in the control group (p = 0.40). Multivariable logistic regression analysis showed a reduced, but non-significant risk of PPPD (odds ratio = 0.70, 95% confidence interval = 0.34-1.42). There were no significant associations in secondary outcomes between the intervention and control group.
conclusionsDistributing a booklet alone may not be sufficient to reduce the risk of PPPD. More personalized, interactive, or accessible interventions may be necessary to support paternal mental health during the perinatal period.
