Reliability of the Korean version of the Richards-Campbell Sleep Questionnaire.

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
backgroundSleep disorders are common in critically ill patients. Unfortunately, sleep assessment is challenging in many intensive care units (ICUs). The Richards-Campbell Sleep Questionnaire (RCSQ) is a simple subjective tool that has been validated and used in many countries. This study aimed to evaluate the reliability of the Korean version of the RCSQ (K-RCSQ).
methodsThis prospective, cross-sectional, observational study was conducted in the ICUs of two hospitals. In total, 52 consenting patients answered questionnaires regarding their previous night's sleep (K-RCSQ) and the noise they experienced (range, 0-100).
resultsThe K-RCSQ showed excellent internal consistency of 0.960 by Cronbach's alpha. The mean total score of the K-RCSQ was 41.9±28.9 (range, 0-100). The mean perceived ICU noise score was 40.7±28.1 (range, 0-90). There was a significant linear correlation between noise score and average K-RCSQ score (r=-0.37, P<0.001).
conclusionsThe K-RCSQ demonstrated excellent reliability (internal consistency). This simple tool may help assess sleep quality in critically ill patients and improve the quality of ICU care.
