Incremental peritoneal dialysis with days off vs standard-dose peritoneal dialysis: a propensity-matched study (PD holiday).
Article in International urology and nephrology, 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
purposeThe benefits of incremental peritoneal dialysis (IPD) with days off remain controversial. This study aimed to compare the survival rate between IPD with days off and standard-dose peritoneal dialysis (PD).
methodsParticipants who started continuous peritoneal dialysis (CAPD) between October 1, 2020 and November 30, 2021, in a tertiary hospital in Thailand were enrolled. IPD with two days off (performed 5 days a week) and standard-dose PD (performed every day) were compared using propensity score matching at a 1:1 ratio for baseline characteristics. The primary outcome was 1-year patient survival. One-year PD continuation rate, PD-associated peritonitis rate, admission rate, and weekly Kt/V at 6 weeks, 6 months, and 12 months were analyzed.
resultsThe 118 eligible patients (37 IPD and 81 standard-dose PD) were included. After propensity score matching, the groups were compared. One-year patient survival rates were comparable between groups, with no statistically significant difference (94.3% vs. 97.4% in the IPD and standard-dose PD groups, respectively; hazard ratio (HR) 2.15, 95% confidence interval (CI) 0.19-23.75). The 1-year PD continuation, PD-associated peritonitis rate, and admission rate were comparable between groups. Total weekly Kt/V over the 12 months showed no significant change over time.
conclusionIPD with days off appears to be safe and comparable to standard-dose PD in terms of short-term patient survival.
