Factors associated with survival among patients with end-stage kidney disease undergoing hemodialysis in Tanzania: a cohort study.
Article in BMC nephrology, 2026. 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
backgroundDespite increased technological advances and trained health workers, morbidities and mortalities of patients on hemodialysis (HD) treatment remain unacceptably high, and factors affecting survival are largely unknown in Tanzania. This study aims to assess factors associated with survival among patients with end-stage kidney disease (ESKD) undergoing hemodialysis in Tanzania.
methodsThis retrospective study involved 386 patients with ESKD aged 18 years and older who underwent HD at Muhimbili National Hospital (MNH) hemodialysis unit from January 2016 to December 2021. The Kaplan-Meier method was used to determine the survival rate of patients, and the Cox proportional hazard model was used to evaluate the factors associated with survival.
resultsOverall, 386 participants were enrolled in the study, with a mean age of 50.7 ± 15.87 years, and the median survival time was 2.5 years. The estimated survival rates for 1-, 2-, and 3-year were 66%, 53%, and 47%, respectively. In the multivariable model, patients with higher risks of mortality were those in the age group ≥ 56 years (Hazard ratio, HR = 2.19, 95% confidence interval, CI: 1.35, 3.53; P = 0.001), with primary education (HR = 2.02, 95%CI: 1.15, 3.54; P = 0.014) and secondary education (HR = 1.81, 95%CI: 1.03, 3.18, P = 0.039), unemployed (HR = 1.83, 95%CI: 1.10, 3.03, P = 0.019), catheter vascular access (HR = 1.44, 95%CI: 1.05, 0.97; P = 0.023); WBC count (HR = 1.38, 95%CI: 1.02, 1.86; P = 0.038) and platelets count (HR = 1.79, 95%CI: 1.29, 2.50; P = 0.001) not in a normal ranges. Patients with a lower risk of mortality were those whose ESKD was due to renal causes (HR = 0.42, 95% CI: 0.18, 0.97; P = 0.041) and those whose model of payment for treatment was Health insurance (HR = 0.58, 95% CI: 0.40, 0.83; P = 0.003).
conclusionThe results showed that the survival rates for 1-, 2-, and 3-year were 66%, 53%, and 47%, respectively. Younger age, college or university education, employment, health insurance, fistula vascular access, and normal range WBC count and platelet count were factors associated with higher survival rates.
