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
backgroundAdolescents with Type 1 diabetes are at increased risk of eating disorders, which have been associated with suboptimal metabolic control and an increased risk of complications. Reliable and culturally adapted screening tools are essential for early identification. However, the parent-reported version of the Diabetes Eating Problem Survey-Revised (DEPS-R) has not yet been validated in Turkish; therefore, this study aimed to evaluate its validity and reliability in adolescents aged 10-17 years years with type 1 diabetes.
methodsThis methodological validation study included 96 adolescents (45 boys, 51 girls) aged 10-17 years with Type 1 diabetes and their parents. Linguistic and cultural adaptation procedures were conducted in accordance with standard cross-cultural validation guidelines. Parents completed the parent-reported DEPS-R and the Problem Areas in Diabetes-Parents of Teens (P-PAID-T). Adolescents completed the self-reported DEPS-R. Construct validity was assessed using correlation analyses. Exploratory and confirmatory factor analyses were performed to evaluate structural validity. Internal consistency was assessed using Cronbach's alpha, and test-retest reliability was examined using intraclass correlation coefficients (ICC).
resultsThe parent-reported DEPS-R demonstrated good internal consistency (Cronbach's α = 0.852; McDonald's ω = 0.851) and good test-retest reliability (ICC = 0.83), with a strong correlation between the two administrations (r = 0.89). Exploratory and confirmatory factor analyses supported a single-factor structure and demonstrated with acceptable model fit (χ²/df = 1.629; RMSEA = 0.080; CFI = 0.874; TLI = 0.848). Parent-reported DEPS-R scores were correlated with self-reported DEPS-R scores (r = 0.506, p < 0.001) and P-PAID-T scores (r = 0.458, p < 0.001), supporting construct validity. A positive correlation was also observed between duration of diabetes and DEPS-R scores (r = 0.223, p = 0.029). No significant associations were observed between DEPS-R scores and metabolic indicators, including HbA1c, ketoacidosis episodes, or diabetes-related hospital visits.
conclusionThe Turkish parent-reported DEPS-R is a valid and reliable instrument for screening disordered eating behaviors in adolescents with Type 1 diabetes. Its use in both clinical and research settings may facilitate early detection and improve understanding of the relationship between eating behaviors and metabolic outcomes in this high-risk population.
