Prevalence and maternal-fetal outcomes of early-onset versus late-onset of preeclampsia: a prospective cohort study at Wallaga university compressive specialized hospital.
Article in BMC pregnancy and childbirth, 2026. 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
backgroundPreeclampsia is a multisystem disorder and is one of the leading causes of maternal and perinatal morbidity and mortality worldwide, particularly in developing countries like Ethiopia. Therefore, this study aim to asses the prevalence and feto-maternal outcome of early onset of preeclampsia and late onset of Preeclamsia in selected hospitals in Nekemte City. MATERIALS AND
methodsA Facility-based prospective cohort study was conducted at Wallaga University compressive specialized Hospital from December 2024 to June 2025. A total of 104 pregnant women with Preeclampsia were recruited for this study. Data were entered into Epi Info version 3.1, transferred, and analyzed using SPSS version 27.0. Categorical variables are presented as frequencies and percentages. Differences between the early-onset and late-onset groups were assessed using the Chi-square test. For tables with small expected cell counts (<5), Fisher’s Exact test was employed. P-value < 0.05 was considered statistically significant.
resultLate-onset preeclampsia was significantly more prevalent than early-onset (70.2% vs. 29.8%, p<0.001). Infants in the early-onset group had significantly lower birth weights and poorer Apgar scores at 1 and 5 minutes (all p<0.05). Gestational age at delivery was a critical factor for neonatal survival (p<0.001), with all cases of intrauterine and neonatal death occurring in the early-onset group. The mode of delivery and rates of major maternal complications did not differ significantly between the two groups. Most women in both groups showed improvement and were discharged.
conclusionThis study confirms that early-onset preeclampsia, though less common, carries significantly higher risks of adverse neonatal outcomes, including mortality, compared to late-onset preeclampsia. We recommend enhanced fetal monitoring and delivery planning at advanced care facilities for early-onset cases to improve survival.
