Circulating RIPK3 level predicts all-cause mortality in patients on maintenance hemodialysis: a 4-year prospective cohort study.
Article in BMC nephrology, 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
backgroundMaintenance hemodialysis (MHD) is a well-established modality of renal replacement treatment for patients with end-stage renal disease. Currently, receptor-interacting protein kinase-3 (RIPK3) is considered as a key regulator of inflammation. But its association with mortality in MHD patients remains unclear. Thus, the aim of the present study was to observe the predictive value of plasma RIPK3 for all-cause mortality in patients undergoing MHD with a 4-year follow-up.
methods148 patients undergoing MHD treatment during June 2020 were enrolled. The plasma RIPK3 levels were measured via enzyme-linked immunosorbent assay. Patients were followed up for 4 years to record all-cause mortality until June 2024.
resultsDuring the 4-year follow-up period, the total incidence of all-cause mortality was 34.46% (51 of 148 participants). Compared with the survival group, the non-survival group presented significantly greater age, diabetes prevalence, serum hs-CRP, plasma RIPK3, and lower serum albumin levels. Cox multivariate analysis revealed an independent association between plasma RIPK3 levels and all-cause mortality. The optimal cutoff value to predict all-cause mortality in patients receiving MHD was 251.54 ng/mL with the AUC of 0.7 (95% CI 0.61-0.79). Kaplan-Meier estimates showed a significantly greater overall survival probability for patients with RIPK3 concentrations lower than 251.5 ng/mL than for those with RIPK3 concentrations ≥ 251.5 ng/mL (p < 0.001).
conclusionPlasma RIPK3 level may serve as an independent predictor for all-cause mortality in MHD patients.
