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

backgroundPostpartum depression is experienced by approximately 10% of women and affects the health and development of their children. Although it is recommended that all mothers have the opportunity for early detection and intervention for postpartum depression, it is unclear whether early postpartum check-ups help to reduce postpartum depression.

objectiveThe aim of this study was to assess the effect of 2-week postpartum check-ups on screening positive for postpartum depression in Japan.

methodsThis was a population-based cohort study that used the administrative database of Tsuyama, Japan. Participants were women who received postpartum home visits from a public health nurse in Tsuyama during the fiscal years 2017-2019. Data were obtained on participant's attendance at a 2-week postpartum check-up and their responses on the Edinburgh Postpartum Depression Scale. Owing to the initiation of a publicly funded postpartum check-up programme, participants were pseudo-randomly assigned to receive/not receive a 2-week postpartum check-up. We conducted instrumental variable estimation to assess the causal effects of the check-up on screening positive for postpartum depression.

resultsThe characteristics of the 1,382 participants did not differ by fiscal year of childbirth. We found a 6.7% (95% confidence interval 2.2-11.2) reduction in the prevalence of screening positive for postpartum depression as an effect of 2-week postpartum check-ups among women received 1-month postpartum home visits.

conclusionThe results suggest that 2-week postpartum check-ups are effective in reducing the prevalence of screening positive for postpartum depression among 1-month postpartum women. Despite some limitations, early postpartum care could reduce postpartum depression.
