Prevalence and risk factors of stillbirths among pregnant women from twelve high-volume birthing facilities of Karachi, Pakistan: a longitudinal cohort study.
Article in BMC pregnancy and childbirth, 2025. 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
backgroundStillbirth, defined as the death of a fetus at or after 22 weeks of gestation, remains a neglected public health issue, with approximately 2 million stillbirths occurring annually. Pakistan ranks among the top three countries with the highest number of stillbirths, yet progress in reducing stillbirth rates remains slower than regional and global averages. Despite the substantial burden, there is a lack of evidence on the prevalence, geographic variation, and predictors of stillbirths in Pakistan, particularly from marginalized settings.
methodsWe conducted a longitudinal cohort study in 12 selected public and private birthing facilities located in Karachi, Sindh, Pakistan between February 9, 2021, and January 1, 2022. We enrolled pregnant women visiting the selected birthing sites during antenatal care visits and those directly visiting for deliveries. We used the World Health Organization (WHO) standard definition of stillbirth occurring at a gestational age of ≥22 weeks. We analyzed stillbirth rates across birthing sites, geographic location, and gestational age, and used firth logistic regression to identify risk factors for stillbirths.
resultsOf the pregnant women enrolled (n = 21,523), 63.5% (13,668/21,523) with a gestational age ≥ 22 weeks delivered their babies at the study birthing facilities. The overall weighted stillbirth rate was 12.0 per 1,000 births across all sites. The prevalence varied substantially across sites, geographic location, gestational age, and facility type (public or private). Multivariable logistic regression showed a significant association between polio-endemic super high-risk union councils (AHR: 3.53; CI: 1.84-6.75), preterm delivery (AHR: 3.97; CI: 1.42-11.16), unvaccinated for Tetanus Toxoid (TT) vaccine during pregnancy (AHR: 5.29; CI: 2.61-10.74), and having received <8 ANC visits (AHR: 2.40; CI: 1.04-5.53) with stillbirth outcomes.
conclusionOur study found significant variation in stillbirth prevalence across birthing facilities and geographic locations, with notably higher stillbirth rates in polio-endemic regions. These findings highlight the need for integrated approaches that combine polio eradication efforts with enhanced maternal healthcare services including maternal immunizations to maximize efficiency and impact. Additionally, efforts are needed to ensure high-quality antenatal care services and efficient management of medical conditions and prematurity during pregnancy.
