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: To investigate the psychometric properties of the Chinese version of the Severity of Dependence Scale for stimulant (C-SDS-S) in screening for the DSM-5-defined Stimulant Use Disorder (SUD). Design: Retrospective chart review. Methods: A total of 227 Chinese-speaking stimulant (methamphetamine and cocaine) users were identified from four previous studies conducted in Hong Kong. Their demographic data, frequency of stimulant use within the past 30 days, scorings for C-SDS-S and the severity of SUD at baseline were extracted and synthesized. In addition, test-retest reliability of C-SDS-S was assessed in 101 subjects who reported C-SDS-S scorings 4 weeks after baseline. Findings: The C-SDS-S demonstrated an acceptable internal consistency with a Cronbach's alpha of 0.736. C-SDS-S scorings were associated with the severity of SUD (ρ = 0.292, Conclusion: The C-SDS-S is a valid and reliable screening instrument to identify stimulant users with DSM-5 defined moderate-to-severe SUD in the Chinese-speaking population.
