Interpregnancy interval and maternal postpartum depression and anxiety: findings from the APrON cohort.
Article in European journal of public health, 2026. 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
Shorter interpregnancy intervals (IPI) are linked to adverse maternal health outcomes, such as pre-eclampsia and gestational diabetes mellitus. The link between IPI and maternal mental health has not been examined despite its potential clinical implications. The aim of this study was to examine associations between IPI and postpartum symptoms of depression (PPD) and anxiety (PPA). We retrieved data from the APrON study. Mothers (n = 613) completed the Edinburgh Postpartum Depression Scale to assess depression and the Symptoms Checklist-90 to assess anxiety within 1 year of the second child's delivery. IPI was categorized into <6, 6-11, 12-17, 18-23, 24-59, and 60-119 months. Logistic generalized linear modeling was performed. Mothers ≥35 years of age had twice the odds of PPD (OR = 2.06, 95% CI: 1.25-3.36, P = .0041) compared to mothers <35 years. Mothers with high social support had 54% lower odds of PPD (OR = 0.46, 95% CI: 0.29-0.72, P = .00074) compared to mothers with low social support. Mothers with a history of PPD and/or PPA had 3× greater odds of PPD (OR = 3.00, 95% CI: 1.47-5.96, P = .0020) compared to those without a history. Social support postpartum and history of depression and/or anxiety were also associated with PPA (P < .05). IPI was not related to maternal PPD or PPA in this cohort. Comprehensive mental health support programs and resources are warranted not only postnatally, but prenatally and throughout gestation, particularly in older mothers and those with mental illness history.
