Charlson comorbidity index and all-cause mortality in patients with delayed hemodialysis initiation: a 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. Cited by 6 papers.
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
backgroundChronic kidney disease (CKD) has recently been recognized as a public health issue. Prognosis and risk stratification are fundamental for decision-making to implement patient-centered strategies in clinical practice. Different prognosis scales have been evaluated, such as the Charlson Comorbidity Index (CCI), surprise questions, functional and biochemical parameters, to stratify patients with CKD initiating dialysis. The aim of this study was to determine prognostic factors for mortality in patients with CKD and delayed initiation of hemodialysis (HD).
methodsWe performed a prospective cohort study based on data from a reference dialysis center in the northeastern region of Mexico. Individuals with CKD and delayed initiation of hemodialysis were stratified according to the CCI at admission. Additionally, sociodemographic, functional, and biochemical parameters were compared to assess all-cause mortality.
resultsA total of 218 patients were included, with a median follow-up of 45.5 weeks. An important proportion of all-cause mortality was associated with infections among all groups. At the end of follow-up, overall all-cause mortality was 40%. Patients stratified with a low CCI had a survival rate of 79.2%, whereas those with moderate, high and very high CCIs had survival rates of 66.7%, 56.6%, and 41%, respectively. After adjusting for clinical and biochemical characteristics, patients who answered that they would not be surprised if they died in the following 6 months had an increased risk of all-cause mortality regardless of the CCI category. Patients with a high CCI (HR: 2.52; 95% CI: 1.22-5.18) and very high CCI (HR: 3.73; 95% CI: 1.89-7.36) clearly had increased risk for all-cause mortality.
conclusionIndividualized patient-centered care should be the goal of standard care. By integrating the CCI and the surprise question (would you be surprised if the patient died in the following 6 months), it is possible to guide decisions further therapeutic strategies in patients in resource-limited settings.
