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
objectiveThe health behavior and mental health problems of adolescents have shown a variety of changes due to the coronavirus disease-2019 (COVID-19) pandemic. This study compared health behavior, obesity, and mental health among Korean adolescents before and during the early COVID-19 pandemic.
methodsPopulation-based and cross-sectional data from the 2019 and 2020 Korea Youth Risk Behavior Web-Based Surveys were used. Data of 57,048 and 54,948 adolescents from the 2019 and 2020 surveys, respectively, were compared. Multiple logistic regression analysis was conducted to compare health behavior, obesity, and mental health before and during the COVID-19 pandemic.
resultsThe adjusted odds ratio (aOR) of overweight, obesity, and body image perceived subjectively as fat, were higher in the 2020 sample compared to the 2019 sample. The aOR of the frequency (more than 3 times a week) of fast-food consumption was higher in 2020 than in 2019. However, the aOR of physical activity, alcohol use, and smoking experience were lower in 2020 than in 2019. In addition, during COVID-19, adolescents were less likely to have perceived severe stress, depressive moods, and suicidal ideation.
conclusionCurrent evidence suggests the co-occurrence of positive and negative changes in health behavior, obesity, and mental health among Korean adolescents during the early COVID-19 pandemic. The results contribute insights for monitoring adolescents' health behavior and promoting their mental health during school shutdowns.
