Pregnancy-associated acute kidney injury as an important driver of chronic kidney disease in females in developing countries: A systematic review.

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
introductionPregnancy-related AKI (PR-AKI), has profound maternal and fetal implications, including high mortality and long-term risks such as the development of chronic kidney disease (CKD). This systematic review aims to evaluate the burden of CKD owing to PR-AKI cases during follow-up in developing countries, particularly India.
methodsA systematic search of PubMed, Embase, and Cochrane databases was performed for Indian studies published between 2000 and June 2024. We included cross-sectional, retrospective, and prospective cohort studies that reported the incidence of PR-AKI, subsequent CKD, and dialysis dependency in Indian cohorts during follow-up. Details of etiology of PRAKI, and adverse fetal and maternal outcomes were also recorded. Only studies that provided follow-up kidney outcomes were considered.
resultsA total of 25 studies comprising 2,306 participants were included in the analysis. The incidence of PR-AKI ranged from 1 to 12% across different studies. Sepsis was the most common cause of PR-AKI, accounting for up to 78% of cases, followed by hypertensive disorders, obstetric haemorrhage, and tropical etiologies. Hemodialysis was required in 20-85% of patients. CKD development during follow-up was observed in 12.8-35% of cases, with up to 30% remaining dialysis-dependent. Maternal mortality ranged from 2.5 to 34%, while perinatal mortality reached as high as 67.3%. Pre-term delivery rates varied between 13.9% and 58%.
conclusionsUp to one-third of PR-AKI patients may develop CKD and remain dialysis-dependent during follow-up. PR-AKI significantly impacts both maternal and fetal morbidity and mortality. Early prevention and prompt management by healthcare professionals are critical to improving outcomes in PR-AKI. Pregnancy-related acute kidney injury (PR-AKI) significantly affects maternal and fetal health, leading to high mortality and long-term complications such as chronic kidney disease (CKD). This systematic review, focusing on developing countries like India, evaluated the burden of CKD due to PR-AKI patients. The review analyzed Indian studies published between 2000 and June 2024, including 25 studies with 2,306 participants. PR-AKI incidence ranged from 1 to 12%, with sepsis being the leading cause in up to 78% of cases, followed by hypertensive disorders, obstetric hemorrhage, and tropical fevers. RRT was needed in 20-85% of patients, and 12.8-35% developed CKD during follow-up, with up to 30% remaining dialysis-dependent. Maternal mortality varied from 2.5 to 34%, while perinatal mortality reached 67.3%. The study emphasizes the critical need for early prevention timely intervention and need for long-term follow-up to reduce the high morbidity and mortality rates associated with PR-AKI.
