Nephrotic Range Proteinuria in Preeclampsia Associated With Adverse Pregnancy Outcomes in Comparison to Non-nephrotic Range Proteinuria: A Prospective Cohort Study.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
AIMS AND
objectivesTo compare pregnancy outcomes among pre-eclamptic women with nephrotic and non-nephrotic range proteinuria.
methodsThis prospective cohort study was conducted from May 2021 to December 2022 at a tertiary care university hospital in South India. We included a total of 278 women diagnosed with preeclampsia, 56 with and 222 without nephrotic range proteinuria in a 1:4 ratio, respectively. The relative risks (RR) of core maternal and perinatal adverse outcomes for preeclampsia among the two groups were compared. Using logistic regression analysis, we calculated the odds ratio adjusted for maternal characteristics (aOR).
resultsThe women with nephrotic range proteinuria had a higher risk of eclampsia (RR 4.29, 95% CI 2.07-8.89, p<0.01), hemolysis, elevated liver enzymes, low platelet (HELLP) syndrome (RR 6.79, 95% CI 2.8-16.46, p<0.01), abruptio placentae (RR 4.95, 95% CI 2.05-11.97, p<0.01), pulmonary oedema (RR 5.94 95% CI 2.55-13.84, p<0.01), acute kidney injury (RR 4.75 95% CI 1.5-15.02, p 0.003), retinal detachment (RR 23.78 95% CI 2.92-193.5, p <0.01), stillbirth (RR 7.48 95% CI 3.52-15.89, p<0.001), small for gestational age (RR 1.45 95% CI 1.27-1.65, p <0.001), respiratory support (RR 2.06 95% CI 1.12-3.76, p<0.02) and neonatal mortality (RR 3.3 95% CI 1.04-10.43, p 0.04) compared to non-nephrotic range proteinuria. Most of the women with nephrotic proteinuria had early-onset preeclampsia (64.28% versus 36.03%, p<0.01), increasing the risk of prematurity and neonatal morbidity and mortality.
conclusionIn women diagnosed with preeclampsia, the nephrotic range proteinuria was associated with poor maternal and perinatal outcomes and should be considered as a predictor of adverse pregnancy outcomes.
