Prognostic Significance of Baseline Lean Tissue Mass Percentage in Incident Peritoneal Dialysis Patients.
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: Bioimpedance spectroscopy is a convenient method to measure lean tissue mass (LTM), which is commonly taken as the skeletal muscle mass, in peritoneal dialysis (PD) patients. We investigated the prognostic significance of LTM as the percentage of body weight (%LTM) and as the marker of sarcopenia in incident PD patients. Study Design: A retrospective review of a prospective cohort. Setting & Participants: 349 incident PD patients in a single center. Predictor: Baseline %LTM. Outcomes: Patient survival, technique survival, peritonitis-free survival, peritonitis rate, hospitalization rate, and the duration of hospitalization. Analytical Approach: Time-to-event survival analyses; linear regression for hospitalization. Results: The 5-year patient survival rates were 50.2%, 55.3%, 61.0%, and 72.6% for patients with %LTM quartiles I-IV, respectively (log-rank test; Limitations: Observational study with baseline measures only. Conclusions: Baseline %LTM as measured using bioimpedance spectroscopy is associated with patient survival, peritonitis-free survival, the number of hospital admissions, and the duration of hospital stay in incident PD patients.
