Adverse perinatal outcomes and associated factors among mothers of advanced age at a tertiary hospital, Southwestern Uganda: a cross-sectional 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
backgroundPregnancies among mothers of advanced age (≥ 35 years) are inherently associated with poor perinatal outcomes. In this study, we determined the proportion of adverse perinatal outcomes and identified associated factors among pregnant mothers of advanced age who delivered at Kabale Regional Referral Hospital (KRRH) in Southwestern Uganda.
methodsWe conducted a cross-sectional study at KRRH's Maternity Ward from March to August 2023. We enrolled post-delivery mothers aged ≥ 35 years. We collected data on socio-demographic, obstetric, and medical characteristics, as well as fetal outcomes, using interviewer-administered structured questionnaires. We defined an adverse perinatal outcome as the occurrence of any of the following complications: early neonatal death, preterm birth, congenital anomalies, macrosomia, low APGAR score, or low birth weight, sustained by the fetus or neonate during pregnancy, delivery, or the immediate post-delivery period before discharge from the hospital. We performed multivariable logistic regression to identify factors associated with adverse perinatal outcomes.
resultsWe enrolled 417 participants, of whom 206 (49.4%) were aged 35-37 years. The majority (n = 273; 65.5%) were multiparous (parity ≥ 5). Adverse perinatal outcomes occurred in 8.4% (n = 36; 95% CI: 6.1-11.5%) of participants, with early neonatal death being the most common (3.6%), followed by low birth weight (2.4%), congenital anomalies (2.6%), macrosomia (1.4%), low APGAR score (1.4%), and preterm birth (1.2%). Prolonged labor (adjusted odds ratio [aOR] = 3.71, 95% CI: 1.40-9.85) and a history of abortion (aOR = 2.56, 95% CI: 1.17-5.60) were significantly associated with adverse fetal outcomes.
conclusionApproximately 1 out of every 10 advanced-aged mothers surveyed experienced a poor perinatal outcome, with mothers who had prolonged labor or history of abortions having increased odds of the poor perinatal outcomes. We recommend strengthening close monitoring of labour and timely interventions to reduce adverse perinatal outcomes including early neonatal deaths.
