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
objectivesThis study aimed to investigate the effects of physical activity and mental health on chewing difficulty in South Korean adults using data from the seventh Korea National Health and Nutrition Examination Survey (KNHANES VII, 2016-2018).
methodsA total of 8212 participants aged ≥20 years who completed surveys on their physical activity, mental health, and chewing status were included. Chewing difficulty was assessed via a five-point Likert scale based on self-reported discomfort when chewing due to oral problems, and dichotomized for analysis. The participants were divided into two groups: those aged <40 and those aged ≥40 years. Complex sample analyses, including cross-tabulations and logistic regression, were used to examine the associations.
resultsAmong men aged <40, high perceived stress was associated with 1.71 times higher odds of experiencing chewing difficulty (
conclusionsPerceived stress, insufficient sleep, and depression are significant mental health factors associated with chewing difficulty in adults. These findings emphasize the necessity of a multifaceted approach, including psychosocial mental health issues, to effectively manage chewing difficulty in this population.
