The dilemma of chronic kidney disease and end-stage kidney disease following pre-eclampsia: a literature review and meta-analysis.

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
purposePre-eclampsia (PE) is a pregnancy-related multisystem syndrome, characterized by the sudden onset of hypertension after 20 weeks' gestation. Although previous studies and meta-analyses found an association between pre-eclampsia and chronic kidney disease or end-stage kidney disease later in life, it remains unclear whether this relationship is causal. Furthermore, research conducted to date has not consistently excluded women with chronic hypertension and/or kidney disease prior to pregnancy, indicating a possible selection bias. Therefore, we undertook a systematic review of the updated literature on renal outcomes in women who were healthy prior to pregnancy and experienced pre-eclampsia.
methodsWe searched PubMed-MEDLINE and Embase for eligible studies. We included retrospective and prospective studies involving healthy women with pre-eclampsia and reporting kidney outcomes. Of the 2,796 titles originally screened, 9 studies met our inclusion criteria. A random effects meta-analytic model was used for statistical analysis.
resultsA statistically significant increase in the risk of developing chronic kidney disease and end-stage kidney disease later in life following pre-eclampsia was found (meta-analytic risk ratios [95% confidence interval]: 1.83 [1.16-2.89] and 8.96 [4.94-16.23], respectively), with high statistical heterogeneity. However, the only prospective study did not find a significant association between pre-eclampsia and chronic kidney disease.
conclusionsAlthough a significant association was identified, its clinical relevance and causality remain unclear. Postpartum medical investigation in women affected by pre-eclampsia is essential, but long-term follow-up may not be indicated in the absence of underlying conditions. Only prospective studies could clarify the relationship between pre-eclampsia and kidney disease in women who were healthy before pregnancy.
