Validation of the Korean version of the Clinical Opiate Withdrawal Scale.
Article in Frontiers in public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: The use of prescription opioids has risen dramatically in South Korea in recent years; however, there is no standardized Korean-language instrument to assess opioid withdrawal. The Clinical Opiate Withdrawal Scale (COWS) is a widely used clinician-rated measure for assessing the severity of opioid withdrawal. We aimed to validate the Korean version of the COWS (K-COWS) among patients receiving opioid therapy. Methods: We translated and culturally adapted the 11-item COWS into Korean. A total of 66 adult patients with opioid use disorder who were experiencing withdrawal symptoms were assessed. Each patient was evaluated using the K-COWS and completed the Subjective Opiate Withdrawal Scale (SOWS), the brief 3-item Opioid Craving Scale (OCS-3), and the single-item Opioid Craving Visual Analog Scale (OC-VAS). We examined the internal consistency, factor structure [through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA)], and convergent/discriminant validity of the K-COWS. Results: The K-COWS showed good internal consistency (Cronbach's Conclusion: The K-COWS is reliable and has demonstrated construct validity for withdrawal severity in Korean clinical settings. Given the preliminary nature of the factor structure, the total score is recommended for clinical decision-making. Future studies should assess inter-rater reliability and confirm the structure in larger, more diverse samples.
