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
Objectives: This study investigated the trajectories of subjective happiness among children aged 8-13, assessed the impact of the COVID-19 pandemic, and identified child- and family-level predictors of variations in happiness. Methods: Drawing on 5855 person-years of data from the nationally representative Panel Study on Korean Children, we employed longitudinal multilevel modeling to examine trends, including those during the pandemic period, and to estimate the influence of child- and family-level predictors. Sex differences were analyzed using interaction terms and stratified analyses. Results: The study revealed a significant negative temporal trend in children's subjective happiness from ages 8 to 13 years, with a sharp decline associated with the onset of the pandemic in 2020 (b=-1.524, p<0.001). Regarding child-level predictors, male sex, sleep duration, subjective health, and number of friends were positive predictors. Maternal education was a positive family-level predictor, whereas maternal stress was a negative predictor. In terms of sex differences, the happiness levels of both males and females remained significantly below the pre-pandemic levels. Overweight/obesity, sleep duration, maternal education level, and paternal subjective health were significant predictors among females but not among males. Conclusion: Although we found a decline in happiness with age, we confirmed that COVID-19 had a significant impact on children's subjective happiness. Our findings underscore the need to identify the key predictors of happiness and to consider proactive strategies to prepare for future infectious disease outbreaks.
