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
Introduction Tobacco addiction remains a major public health issue in Indonesia, with smoking cessation often hindered by withdrawal symptoms. The Minnesota Tobacco Withdrawal Scale (MTWS) is a widely used assessment tool, but no validated Indonesian version has been available. This study aimed to translate, validate, and assess the reliability of the Indonesian MTWS. Methods A cross-sectional study was conducted from August to December 2022 with 174 adult smokers. The MTWS was translated and reviewed by five addiction specialists. Content validity was assessed using the Scale-Level Content Validity Index (S-CVI), construct validity through correlation analysis and exploratory factor analysis (EFA), and reliability via Cronbach's alpha. Results The content validity analysis showed that six statements had an Item Content Validity Index (I-CVI) score of 1.0, while 11 statements scored 0.8, resulting in an overall Scale Content Validity Index/Average (S-CVI/Ave) score of 0.87, indicating strong content validity. Construct validity testing revealed that all items had correlation coefficients exceeding the critical r-value (0.124), confirming their validity. EFA indicated a strong factor structure, with a Kaiser-Meyer-Olkin (KMO) value of 0.970 and a Bartlett's Test of Sphericity p-value <0.001. Reliability testing demonstrated high internal consistency, with a Cronbach's alpha of 0.923. Conclusion The Indonesian MTWS is a valid and reliable tool for assessing smoking withdrawal symptoms, supporting healthcare professionals in smoking cessation efforts.
