Impact of obesity on in-hospital outcomes in peritoneal dialysis patients: insights from a nationwide analysis.
Article in International urology and nephrology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundObesity is a growing public health concern and may influence outcomes in end-stage kidney disease (ESKD) patients undergoing peritoneal dialysis (PD). However, its impact on in-hospital complications, mortality, and healthcare utilization in this population remains unclear. This study aimed to assess the association between obesity and hospitalization-related outcomes in PD patients.
methodsThis study was conducted using the National Inpatient Sample to identify hospitalized ESKD patients receiving PD from the year 2003 to 2018. The in-hospital treatments, outcomes, and resource utilization were compared between obese and non-obese patients, adjusting for age, sex, race, year of hospitalization, and comorbidities.
resultsA total of 100,523 hospitalized ESKD patients receiving PD were included in the analysis. Of these, 9890 (9.8%) had obesity diagnosis. In the adjusted analysis, obese patients had a higher need for procedures for PD catheter adjustment or removal (OR 1.29; 95% CI 1.16-1.43), hemodialysis (OR 1.28; 95% CI 1.19-1.38), and mechanical ventilation (OR 1.29; 95% CI 1.16-1.44), compared to non-obese patients. Obesity was significantly associated with higher risk of PD peritonitis (OR 1.12; 95% CI 1.06-1.19) and fluid overload (OR 1.34; 95% CI 1.23-1.45) but lower in-hospital mortality (OR 0.84; 95% CI 0.73-0.96). There was no significant difference in length of hospital stay and hospitalization cost between obese and non-obese patients.
conclusionAmong hospitalized PD patients, obesity is associated with higher PD-related complications and increased need for interventions but is paradoxically linked to lower in-hospital mortality. These findings provide new insights into the obesity paradox in PD and highlight the need for tailored management strategies to mitigate obesity-related risks in hospitalized PD patients.
