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

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundUltraprocessed food (UPF) consumption is very common among adolescents. Previous studies have suggested an association between UPF consumption and adolescent mental health problems, but studies on multiethnic adolescents in China are rare.
objectiveThis study investigated the association between UPF consumption and depressive symptoms in multiethnic adolescents in Yunnan Province, China.
methodsA cluster sampling of 8500 middle school students from 11 counties in Yunnan Province was conducted. The Chinese version of the Depression Anxiety Stress Scale-21 was administered to assess depressive symptoms, and a food frequency questionnaire was used to collect UPF consumption data. A generalized linear model was used to analyze the association between UPF consumption and depressive symptoms, and a restricted cubic spline was used to fit the correlation plot. The association analysis was performed after adjusting for demographic and confounding variables that might have influenced depressive symptoms.
resultsThe detection rates of depressive symptoms in adolescents were 28.3% (2402/8500) for the sample, 25.5% (1069/4184) for males, and 30.9% (1333/4316) for females. After adjusting for confounding variables, instant food (all participants: β=.22, 95% CI 0.13-0.32; P<.001; males: β=.15, 95% CI 0.03-0.27; P=.01; females: β=.29, 95% CI 0.15-0.43; P<.001), carbonated beverage (β=.20, 95% CI 0.12-0.29; P<.001; β=.15, 95% CI 0.04-0.26; P=.006; β=.29, 95% CI 0.16-0.43; P<.001;), energy beverage (β=.21, 95% CI 0.10-0.32; P<.001; β=.22, 95% CI 0.08-0.36; P=.002; β=.22, 95% CI 0.04-0.40; P=.01), and other beverage (β=.24, 95% CI 0.14-0.34; P<.001; β=.21, 95% CI 0.08-0.35; P=.002; β=.25, 95% CI 0.10-0.41; P=.001) consumption were associated with depressive symptoms for all participants, males, and females, respectively. Females were more sensitive to the association between UPF consumption and depressive symptoms. Moreover, female interaction with instant foods (β=.31, 95% CI 0.18-0.44; P<.001), carbonated beverages (β=.27, 95% CI 0.15-0.39; P<.001), energy beverages (β=.18, 95% CI 0.01-0.35; P=.04), and other sugar-sweetened beverages (β=.17, 95% CI 0.02-0.32; P=.03) was associated with depressive symptoms, respectively.
conclusionsThese results indicated that UPF consumption was related to depressive symptoms in Yunnan multiethnic adolescents. Health education and behavioral interventions that reduce UPF consumption could protect adolescents from depressive symptoms.
