1 · What the graph read from it

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.

2 · The registry

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

Introduction: Peritoneal dialysis (PD) is the most prevalent home-based dialysis therapy. However, chronic exposure to metabolically imbalanced high-glucose PD fluids is associated with infectious complications and morphological changes that limit PD duration and patient survival. Here, we analyzed interactions among peritoneal cell immune function, inflammation, and glucose metabolism in a prospective cohort study of patients on PD. Methods: In 117 patients (mean follow-up: 2.15 years), samples from peritoneal equilibration tests (PETs) were assessed for interleukin (IL)-6 levels as a measure of peritoneal inflammation, and Results: Peritoneal inflammation correlated negatively with peritoneal cell immune function and positively with increased risk of subsequent peritonitis (hazard ratio: 3.8). Patients with higher peritoneal inflammation had an altered peritoneal metabolomic profile, with significant perturbation of glucose and amino acid metabolism. Immunometabolic intervention with alanyl-glutamine (AlaGln) supplementation of PD fluid restored immune cell function specifically in patients with high peritoneal inflammation, highlighting the potential to prevent subsequent infections. Conclusion: These results provide the first direct, longitudinal evidence linking immunometabolism with peritoneal glucose exposure, local inflammation, as well as impaired peritoneal cell function and infection in a human PD cohort. Metabolic intervention designed to restore adequate peritoneal cell immune function represents a novel therapeutic approach with promise for improved clinical outcomes in chronic PD.
