Prevalence and risk factors associated with severe features of pre-eclampsia among women in Thailand.
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
objectiveThe objective of this study is to investigate the prevalence of and identify risk factors associated with pre-eclampsia with severe features (sPE) and model such data to generate a predictive risk score. MATERIAL AND
methodThis retrospective case-control study was conducted at Bhumibol Adulyadej Hospital (BAH), between January 2017 and December 2024. Participants were pregnant women who delivered at BAH. Subjects who were diagnosed with sPE and normal were classified as the study and control groups. Data was collected from medical records.
resultThere were 30,620 deliveries during the study period. A total of 546 sPE cases were recruited. There were 500 participants in each group. The significant risk factors associated with sPE were BMI ≥ 25 kg/m2 (aOR: 2.05, 95%CI: 1.43-2.93), age ≥35 years (aOR: 2.33, 95%CI: 1.55 - 3.47), illicit drug use (aOR: 6.47, 95%CI: 2.29 - 18.33), chronic hypertension (CHT, aOR: 10.24 , 95%CI: 4.71, 22.26), diabetes mellitus (DM, aOR: 8.58, 95% CI: 2.46 - 29.93), familial history of hypertension (FHT, aOR: 1.62, 95% CI: 1.1- 2.37) and previous history of preeclampsia (PEPP, aOR: 13.42, 95% CI: 2.95 - 61.04).The cut-off was established at a score of ≥ 4, which provided sensitivity, specificity, positive and negative predictive value, and accuracy at 54.2, 87.0, 80.7, 65.5 and 70.6 percent respectively.
conclusionThe prevalence of sPE was 17.8 per 1,000 deliveries. PEPP, CHT, DM, illicit drug use, advanced age (≥35 years), BMI ≥25 and FHT were associated with higher risk of sPE development at aOR of 13.42, 10.24, 8.58, 6.47, 2.3, 2.05 and 1.62, respectively.
