Reliability and validity of the Korean version of the University of California-Los Angeles Scleroderma Clinical Trial Consortium Gastrointestinal Tract instrument in patients with systemic sclerosis.
Article in The Korean journal of internal medicine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND/
aimsSystemic sclerosis (SSc) is associated with a wide range of gastrointestinal (GI) changes. The University of California-Los Angeles Scleroderma Clinical Trial Consortium Gastrointestinal Tract (UCLA SCTC GIT 2.0) instrument is a self-administered GI assessment instrument for patients with SSc. We developed a Korean version of the UCLA SCTC GIT 2.0 instrument and evaluated its reliability and internal consistency.
methodsThe participants were 37 Korean patients with SSc. Translation and cross-cultural adaptation of the UCLA SCTC GIT 2.0 were performed according to international standardized guidelines. We evaluated reproducibility by calculating the intraclass correlation coefficients and assessed the internal consistency of the Korean version of the UCLA SCTC GIT 2.0. We assessed its construct validity by evaluating its correlations with the Short Form Health Survey version 2 and EQ-5D scores by means of Spearman correlation analyses.
resultsPatients with SSc were mostly women (89.19%) with a mean age of 52.2 years, median disease duration of 24 months, and median modified Rodnan total skin score of 4. The median total GIT score on the UCLA SCTC GIT 2.0 was 0.3. The UCLA SCTC GIT 2.0 Korean version showed excellent internal consistency (Cronbach's α of total GIT score = 0.863). Most domains of the ULCA SCTC GIT 2.0 were correlated with those of the EuroQol (EQ)-5D score.
conclusionThe Korean version of the UCLA SCTC GIT 2.0 has acceptable internal consistency, reliability, and validity. Therefore, it can be used to assess GIT involvement in Korean patients with SSc.
