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
The aim of this study was to assess the validity and reliability of the Turkish version of the Dimensional Anhedonia Rating Scale (DARS-TR) in a clinical sample of adolescents, including those diagnosed with Major Depressive Disorder (MDD), individuals at ultra-high risk for psychosis and/or psychotic individuals (UHR/PSYC), and healthy controls (HC). The study included 63 cases diagnosed with MDD and 59 cases evaluated as UHR/PSYC, aged between 12-18 years, who were admitted to the child and adolescent psychiatry outpatient clinic. 58 age-matched healthy children constituted the control group. The construct validity of the scale was evaluated through factor analysis. Internal consistency was analyzed using Cronbach's α and McDonald's ω. For the assessment of convergent, concurrent, and divergent validity, the Snaith-Hamilton Pleasure Scale (SHAPS), the Behavioral Activation System/Behavioral Inhibition System Scale (BAS/BIS), and the Children's Depression Rating Scale-Revised (CDRS-R) were employed. There was a strong correlation between total DARS scores and SHAPS, BAS, and the anhedonia-related item of CDRS-R (p < 0.001). However, no significant relationship was found with BIS score. DARS items demonstrated excellent internal consistency (Cronbach's α = 0.92, McDonald's ω
