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
Objective: Methamphetamine abuse has been a growing global problem. A variety of psychiatric problems might emerge due to chronic methamphetamine use. The aim of this study was to evaluate the psychometric properties of the Turkish version of the 10-item Amphetamine Withdrawal Questionnaire Version 2 (AWQv2). Method: A total of 220 participants admitted to the outpatient treatment clinic for methamphetamine use were included in the study. The reliability and internal consistency of the items were examined using Cronbach's alpha. The validity of the scale was assessed through construct and convergent validity. Data were collected with the Turkish version of the Amphetamine Withdrawal Questionnaire, Montgomery-Asberg Depression Rating Scale (MADRS), Hamilton Anxiety Rating Scale (HARS), Clinical Global Impressions - Severity Scale (CGI-S), and Penn Drug Craving Scale. Results: The majority of the group was male (84.4%). The mean age was 29.7±6.7. Half of the participants were daily methamphetamine users (50%), with most preferring inhalation (94.8%). The scale's internal consistency was found to be Cronbach's alpha of 0.80. For test-retest reliability, the Spearman rank-order correlation coefficient was high (0.83). Factor analysis using exploratory factor analysis yielded a two-factor model: affective and reversed vegetative factors. The convergent validity of the scale showed positive and significant correlations with other scales (MADRS, r=0.769, p<0.001; HARS, r=0.709, p<0.001; CGI-S, r=0.742, p<0.001; Penn Substance Craving Scale, r=0.510, p<0.001). Conclusion: The Turkish version of the AWQv2 is a valid and reliable measurement tool for assessing methamphetamine withdrawal symptoms in a clinical sample.
