1 · What the graph read from it

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.

2 · The registry

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

purposeUremic pruritus significantly impairs the quality of life in hemodialysis (HD) patients, a specific assessment tool for this population is lacking. The primary purpose of this study was to translate the Uremic Pruritus in Dialysis Patients (UP-Dial) scale into Turkish and evaluate its validity and reliability.

methodsIn this methodological study, 181 HD patients with pruritus were included. The reliability of the Turkish UP-Dial scale was tested using Cronbach's alpha values for internal consistency. Construct validity was examined via exploratory factor analyses (EFA) and confirmatory factor analyses (CFA). Convergent validity was assessed by correlating the UP-Dial with the Numerical Rating Scale (NRS), 5-D Itch Scale, and Dermatology Life Quality Index (DLQI).

resultsFollowing item analysis, item 7 (xerosis) was excluded due to low item-total correlation. The 13-item Turkish UP-Dial demonstrated excellent internal consistency (Cronbach's α = 0.90) and test-retest reliability (ICC = 0.98; 95% CI = 0.97-0.99). EFA revealed a four-factor structure explaining 78.5% of the total variance, and CFA demonstrated good model fit (χ

conclusionThe 13-item Turkish UP-Dial is a valid and reliable tool for multidimensional assessment of uremic pruritus in HD patients. It may provide standardized follow-up and evaluation of responses to both pharmacologic and non-pharmacologic treatments for uremic pruritus.
