Characteristics and 1-year survival of incident patients on chronic peritoneal dialysis compared with hemodialysis:a large 11-year cohort study.

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
purposeFew studies have evaluated patients' characteristics and survival by dialysis modality in Brazil. We evaluated changes in dialysis modality and its survival in the country.
methodsThis is a retrospective database of a cohort with incident chronic dialysis patients from Brazil. Patients' characteristics and one-year multivariate survival risk were assessed considering dialysis modality from 2011 to 2016 and 2017 to 2021. Survival analysis was also performed on a reduced sample after adjustment using propensity score matching.
resultsOf the 8295 dialysis patients, 5.3% were on peritoneal dialysis (PD) and 94.7% on hemodialysis (HD). PD patients had higher BMI, schooling and the prevalence of elective dialysis starting in the first period than those on HD. In the second period, PD patients were predominantly women, non-white, from the Southeast region, and funded by the public health system, having more frequent elective dialysis starting and predialysis nephrologist follow-ups than those on HD. There was no difference in mortality comparing PD and HD (HR 0.67, 95% CI 0.39-2.42; and HR 1.17, 95% CI 0.63-2.16; first and second period, respectively). This non-significantly different survival between both dialysis methods was also found in the reduced matched sample. Higher age and non-elective dialysis initiation were associated with higher mortality. In the second period, the lack of predialysis nephrologist follow-up and living in the Southeast region increased the mortality risk.
conclusionSome sociodemographic factors have changed according to dialysis modality over the last decade in Brazil. The one-year survival of the two dialysis methods was comparable.
