Epidemiological characteristics and factors associated with chronic kidney disease-associated pruritus in the Chinese adult dialysis population: a multicenter, cross-sectional 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
To our knowledge, no large‑sample epidemiological studies on chronic kidney disease‑associated pruritus (CKD‑aP) have been reported in China in recent years. We aimed to investigate the prevalence and related factors of CKD-aP in Chinese dialysis population. This study included data on 9,589 dialysis patients across 30 provincial-level administrative divisions in mainland China between May 2022 and December 2022. The EQ-5D was used to collect patient information. Pruritus severity was assessed using the Numerical Rating Scale (NRS). Generalized estimating equations (GEE) were used to explore the potential influencing factors of CKD-aP. The prevalence of CKD-aP in Chinese adult dialysis patients was 60.3%. The prevalence of mild, moderate, and severe pruritus was 44.4%, 12.5%, and 3.3%, respectively. The prevalence of pruritus, moderate-to-severe pruritus, and severe pruritus in hemodialysis (HD) patients was 59.9%, 16.0%, and 3.4%, respectively. The prevalence of pruritus, moderate-to-severe pruritus, and severe pruritus in peritoneal dialysis (PD) patients was 61.8%, 14.1%, and 2.8%, respectively. No significant difference in pruritus prevalence was observed between HD (59.9%) and PD (61.8%) patients. Only 2.9% of the patients received potentially effective treatment (gabapentinoids 2.8%, kappa opioid receptor agonists 0.1%). Smoking history, diabetic nephropathy, cardiovascular diseases, dialysis vintage, eosinophil count, serum total calcium, and serum phosphorus were factors associated with CKD-aP. CKD-aP is highly prevalent among Chinese dialysis patients, with comparable rates between HD and PD populations. Several modifiable and non-modifiable factors were significantly associated with pruritus. Few patients received potentially effective treatment. These results highlight the potential targets for improving patient management.
