Association of incident dialysis modality with patient survival: a systematic review and meta-analysis.

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
backgroundAlthough the choice of dialysis technique is based on several factors, patient survival is undoubtedly one of the most relevant. In a context where randomization to either peritoneal dialysis (PD) or hemodialysis (HD) proved to be extremely challenging, previous meta-analyses were greatly limited due to the inclusion of historical studies.
methodsWe performed a systematic review by searching multiple databases up to April 22nd, 2022. The primary outcome was the association between dialysis modality (PD vs. HD) and mortality assessed via hazard ratios (HR). Subgroup analyses were conducted to explore potential sources of heterogeneity, including sex, age, diabetes, dialysis vintage, geographical location, HD access, and study cohort inclusion period.
resultsDatabase search yielded 5317 citations, from which, 27 observational studies met the eligibility criteria, including 1 033 362 incident dialysis patients. The pooled mortality HR for PD versus HD was 1.01 (95% CI 0.93–1.10). Heterogeneity was substantial (I2 = 94%) and was largely explained by different baseline features of the included populations. A statistically significant subgroup effect was demonstrated for age (> 65 vs.<65 years; p = 0.01), geographical location of the studies (Oceania vs. Europe vs. Asia vs. North America; p < 0.01), and HD vascular access (central venous catheter vs. arteriovenous fistula; p < 0.01, only one study included).
conclusionsThis meta-analysis suggests that overall PD and incentre HD likely carry equivalent survival benefits. However, differences were detected among subgroups based on age, geographic location, HD access type, but not on sex, diabetes status, dialysis vintage and study cohort inclusion period. CLINICAL TRIAL NUMBER: Not applicable.
