Factors associated with all-cause mortality among patients initiating maintenance hemodialysis: A single-center retrospective cohort study.
Article in Medicine, 2026. 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
Survival outcomes among patients receiving maintenance hemodialysis (MHD) vary considerably across regions and healthcare settings. This study aimed to identify factors associated with all-cause mortality among patients initiating MHD at a county-level hospital in China. In this single-center retrospective cohort study, incident hemodialysis patients treated between 2016 and 2018 were followed until death, censoring, or December 31, 2021. The primary outcome was all-cause mortality. Baseline demographic, clinical, dialysis-related and laboratory variables were compared between patients who died and those who survived or were censored. Survival was estimated using Kaplan-Meier analysis, and factors associated with mortality were examined using multivariable Cox proportional hazards regression. A total of 144 patients were included, of whom 90 died during follow-up. The Kaplan-Meier estimated 1-, 2-, and 3-year survival rates were 73.6%, 56.9% and 46.0%, respectively. In the multivariable Cox model, older age was associated with higher all-cause mortality (hazard ratio [HR] = 1.036, 95% confidence interval (CI): 1.019-1.054, P < .001), as was diabetes mellitus (HR = 4.400, 95% CI: 1.894-10.223, P = .001). Compared with diabetic nephropathy, chronic glomerulonephritis was associated with lower mortality (HR = 0.258, 95% CI: 0.106-0.626, P = .003). Arteriovenous fistula as the initial vascular access (HR = 0.390, 95% CI: 0.233-0.653, P < .001) and higher maintenance dialysis frequency (HR = 0.532, 95% CI: 0.403-0.702, P < .001) were associated with reduced mortality. Older age, diabetes mellitus, DN, initial central venous catheter use, and lower maintenance dialysis frequency were associated with poorer survival among patients initiating MHD. These findings highlight the importance of early risk stratification, vascular access planning and optimization of dialysis delivery in incident hemodialysis care.
