Longitudinal effects of pregnancy on PTSD symptoms in black female participants: Moderation by sexual trauma and progesterone.
Article in Psychoneuroendocrinology, 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
Black pregnant females experience disproportionately higher rates of post-traumatic stress disorder (PTSD) and associated health complications, which may be exacerbated by exposure to sexual trauma. Hormonal fluctuations during pregnancy, including progesterone, may also play a key role in modulating PTSD symptoms. The current study assessed how PTSD symptoms change over pregnancy and how sexual trauma and progesterone independently impact the trajectory of PTSD symptoms in a sample of under-resourced pregnant Black females. Participants (N = 283) completed up to three interviews assessing PTSD symptoms over pregnancy; the enrollment interview assessed pre-pregnancy trauma history. Progesterone concentrations were measured in a subset of participants (N = 91). Results from linear mixed models showed that PTSD symptoms decreased over the course of pregnancy, Β= -0.34, p<.001, and that sexual trauma exposure was associated with higher initial PTSD symptoms, Β = 12.11, p<.001, and a significant decrease in PTSD symptoms across pregnancy, Β = -0.48, p = .002. Individuals with no sexual trauma exposure did not show significant change in PTSD symptoms across pregnancy, Β =-0.14, p = .207. This pattern was observed for total PTSD symptoms and all symptom clusters. In the subset of participants with progesterone data, higher progesterone levels, relative to gestational age, was associated with a greater decrease in PTSD symptoms over pregnancy, Β =-0.01, p = .049. The current findings indicate that individuals with a history of sexual trauma demonstrate higher levels of PTSD symptoms early in pregnancy and suggest that PTSD symptoms may decrease over pregnancy via increasing progesterone levels.
