Maternal and infant outcomes of pregnancy after kidney transplantation: a retrospective cohort study.
Article in Archives of gynecology and obstetrics, 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
purposeTo investigate the effect of postoperative pregnancy on maternal-infant outcomes and transplanted kidney function in kidney transplantation (KT) recipients.
methodsOur study included 104 KT recipients and 104 non-KT women who delivered at four hospitals affiliated with Zhejiang University School of Medicine from December 2015 to November 2023.
resultsIn the KT group, kidney function showed a downward trend after delivery, and most patients recovered normal kidney function within 6 months postpartum. Tacrolimus blood concentration during pregnancy averaged (6.1 ± 1.4) μg/L, increasing to (7.1 ± 2.6) μg/L on the second day after delivery, indicating an upward trend in postpartum concentrations. Compared to the non-KT group, the KT group had higher prevalences of gestational hypertension (33.7% vs. 3.3%), gestational diabetes mellitus (21.2% vs. 17.5%), intrahepatic cholestasis of pregnancy (5.8% vs. 1.7%), placental abruption (1.9% vs. 0.8%), and preterm birth rate (79.8% vs. 9.2%) but had a lower prevalence of fetal growth restriction (8.3% vs. 21.7%). Univariate analysis showed that pre-pregnancy estimated glomerular filtration rate (eGFR), penatal eGFR, gestational hypertension, and preeclampsia may influence neonatal outcomes. Binary logistic regression analysis showed that preeclampsia (odds ratio [OR] = 133.89, 95% confidence interval [CI]: 1.27-156.20, P = 0.031) and hypertension during pregnancy (OR = 5.81, 95% CI: 1.02-33.27, P = 0.048) were risk factors, and glomerular filtration rate during pregnancy (OR = 0.95, 95% CI: 0.90-0.99, P = 0.026) was a protective factor.
conclusionAlthough pregnancies in KT recipients are considered high-risk, the overall risks are manageable. Strengthening the management of KT recipients with reproductive intent is recommended to improve maternal and infant outcomes.
