Touch contamination and associated peritonitis in children undergoing maintenance peritoneal dialysis.
Article in Pediatric nephrology (Berlin, Germany), 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
backgroundInfections are a leading cause of hospitalization and death in children receiving maintenance peritoneal dialysis (PD). Touch contamination is an established risk factor for development of peritonitis, but data regarding optimal management of touch contamination are limited.
methodsWe conducted a retrospective cohort study using data submitted to the Standardizing Care to Improve Outcomes in Pediatric End Stage Kidney Disease (SCOPE) collaborative between 10/1/2011 and 7/31/2025 to evaluate touch contamination in children. Reported touch contamination events and their management, including administration of prophylactic antibiotics and transfer set changes, were evaluated. Univariate and multivariable generalized linear mixed modeling were used to assess relationships between demographic factors and episodes of touch contamination and between management of touch contamination events and temporally associated peritonitis. We also evaluated the microbiology of touch contamination-associated peritonitis and compared it to peritonitis not associated with touch contamination.
resultsOf 2685 children included, 846 (32%) reported at least one touch contamination. In a multivariable model, younger age and non-Hispanic Black race were associated with increased rates of touch contamination. Administration of prophylactic antibiotics following touch contamination was associated with a lower prevalence of peritonitis (23% vs. 38%). Most episodes of touch contamination-associated peritonitis were Gram-positive (46%) or culture negative (24%).
conclusionsTouch contaminations are common in children undergoing maintenance PD. Administration of prophylactic antibiotics following touch contamination is associated with decreased risk of peritonitis.
