Survival of Older Adults Choosing Dialysis or Conservative Kidney Management, Stratified by Suitability for Dialysis.
Article in Kidney 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
Rationale & Objective: Previous studies indicate survival benefit for dialysis over conservative kidney management (CKM), which attenuates in patients ≥80 years or with high comorbidity. Most studies did not differentiate dialysis suitability among those choosing CKM, potentially biasing outcomes. We aimed to describe survival outcomes in patients choosing dialysis, patients suitable for dialysis who chose CKM, and patients less suitable for dialysis who chose CKM. Study design: Single-center cohort study. Setting & Participants: We included patients aged ≥65 years with a documented treatment decision for dialysis or CKM between 2017 and 2024. Exposure: Chosen treatment (dialysis or CKM). Patients choosing CKM were classified as suitable or less suitable for dialysis, based on the treating nephrologist's. Outcome: The primary outcome was all-cause mortality. Analytical Approach: Descriptive, using Kaplan-Meier estimates and Cox proportional hazard models without adjustment for confounding. Results: Median survival from treatment decision was 53 (dialysis), 32 (CKM, suitable for dialysis), and 18 months (CKM, less suitable for dialysis), with unadjusted hazard ratios of 2.11 (CKM, suitable for dialysis vs dialysis; 95% CI 1.59-2.80) and 3.23 (less suitable for dialysis vs dialysis; 95% CI 2.47-4.23). Among patients aged ≥80 years, hazard ratios were 1.89 (0.99-1.74) for CKM suitable for dialysis versus dialysis and 2.35 (1.31-4.64) for CKM less suitable for dialysis versus dialysis. Thirteen percent of patients who initially chose dialysis switched to CKM, whereas 1% transitioned from CKM to dialysis. Limitations: Subjectivity in dialysis suitability assessment. Conclusions: In this cohort of older patients with kidney failure, survival outcomes in patients choosing CKM suitable for dialysis were longer than previously reported. These findings highlight the importance of distinguishing dialysis suitability when evaluating survival outcomes in CKM and dialysis. This supports more individualized shared decision making in older adults with advanced kidney disease.
