Levels of neuroactive steroids are elevated in those who develop first-onset depression early in pregnancy.
Article in Frontiers in psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: Allopregnanolone (ALLO) plays a key role in the pathogenesis of postpartum depression. However, ALLO levels have been variably associated with depression during pregnancy. It is unknown if a pre-pregnancy history of major depressive disorder (MDD), which is associated with blunted neurosteroidogenesis, and timing of perinatal depression (PND) may influence the association between neuroactive steroids (NAS) and PND. Objective: To investigate differences in ALLO and other NAS levels during the first (T1) and second (T2) trimesters based on pre-pregnancy history of MDD and current PND. Methods: Participants completed a diagnostic test of depression, blood samples and mental health history. Ninety-eight participants contributed data in T1 and 93 in T2. Levels of ALLO, pregnanolone (PA), isoallopregnanolone (ISO), epipregnanolone (EPI), and progesterone (P4) were quantified using gas chromatography-mass spectrometry. Analyses of covariance with pairwise comparisons predicted NAS levels from categorized groups of those with: 1) no history of MDD and no PND ( Results: Across groups, there were marginally significant differences in T1 ALLO (p=.05) and ISO levels (p=.05). T1 ALLO levels were higher in the perinatal-emergent versus never depressed (p=.007) and recurrent depression (p=.05) groups. ISO levels were higher in the perinatal-emergent versus recurrent depression (p=.02) and never depressed (p=.03) groups. In T2, there were significant differences in PA levels (p=.04) and marginally significant differences in ALLO (p=.07) and ISO levels (p=.09). ALLO levels were higher in the perinatal-emergent versus recurrent depression group (p=.05), and in the never depressed (p=.05) and pre-pregnancy depression groups (p=.04) compared to recurrent depression. PA levels were higher in the perinatal-emergent depression versus never depressed (p=.02) and recurrent depression (p=.01) groups, and ISO levels were higher in the perinatal-emergent depression versus never depressed (p=.03) and recurrent depression (p=.07) groups. Conclusions: These results suggest differing NAS-related mechanisms of pathogenesis across clinical phenotypes based on pre-pregnancy history of MDD and timing of PND onset. Future research should account for these factors when investigating NAS and PND.
