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.

Abstract
Today's generation children and adolescents are growing up with electronic media. Although the recommended screen time is up to two hours for adolescents, the screen exceeds the recommended limit. Excessive use of screen devices has resulted in decreased sleep and had a negative impact on mental health of adolescents. The objectives of the study were to assess the screen time, sleep quality and mental health among adolescence of secondary schools in Dharan and to find out the association of screen time with socio demographic variables, sleep quality and mental health. Descriptive cross-sectional study was conducted among 259 secondary level students of Dharan. Two government and two private school were selected by simple random sampling technique. Systematic random sampling technique was used to select the respondents. Data was collected using Pittsburgh Sleep Quality Index and Patient Health Questionnaire. Data analysis was done using SPSS version 11.5. The mean screen time of respondents was 4.93 ± 2.11 hours per day and mean sleep duration was 6.73 ± 1.41 hours. The prevalence of poor sleep quality was 40.2% and poor mental health was 46.3%. Screen time was significantly associated with type of school (p = 0.006). There was significant association of sleep quality with screen time for entertainment (p = 0.002), total screen time (p = 0.01) and time of maximum use (p = 0.04). Mental health was significantly associated with screen time for entertainment (p = 0.011) and total screen time (p = 0.013). Mental health score was positively correlated with screen time. This study concludes that adolescents have higher screen time than recommended and a significant proportion of adolescents have poor sleep quality and poor mental health. Screen time is statistically significant and positively correlated with sleep quality and mental health scores.
