Trends and adverse pregnancy outcomes associated with post-traumatic stress disorder: a population-based study of delivery hospitalisations.

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
purposeThis study examined the prevalence of post-traumatic stress disorder (PTSD) diagnoses among pregnant women who delivered in hospitals in the United States between 2016 and 2020, and explored associations with adverse pregnancy outcomes, hospital length of stay, and hospital costs.
methodsThis cross-sectional study utilised survey-weighted data from the Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS) to estimate sample characteristics and prevalence trends. Logistic regression models were used to analyse associations between PTSD and adverse pregnancy outcomes. Length of hospital stay and hospital costs were examined using negative binomial and generalised linear models with log link and gamma distribution, respectively.
resultsPTSD prevalence increased from 236.3 to 545.8 per 100,000 delivery hospitalisations between 2016 and 2020 (p < 0.001; average annual percentage change [AAPC] 23.0%). PTSD was associated with a higher prevalence of comorbidity, increased odds of preterm delivery (adjusted odds ratio [aOR] 1.13; 95% CI 1.08-1.18), and increased odds of fetal growth restriction (aOR 1.09; 95% CI 1.01-1.17, p = 0.03). Longer hospital stays and higher costs were also observed among women with PTSD.
conclusionThese findings highlight a rising prevalence of PTSD among pregnant women who delivered in hospitals in the United States over the study period. PTSD was associated with higher prevalence of comorbidity, and increased length of stay and hospital cost. Further research is warranted to investigate the reasons behind the trend, and to clarify the temporal relationship between prenatal PTSD and adverse pregnancy outcomes.
