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
This study examined the relationship between nutritional intake and mental health, focusing on depressive symptoms among older adults in rural areas. Using data from the 2022 Korea National Health and Nutrition Examination Survey (KNHANES), the nutritional intake of 465 individuals aged 65 and older was analyzed against recommended nutrient intakes (RNI). Mental health was assessed using the PHQ-9 and GAD-7 scales, with logistic regression identifying predictors of depressive symptoms. Results showed deficiencies in essential vitamins, including A, B3 (niacin), C, D, and E. Higher intakes of niacin (≥ 5 mg/day) and Vitamin E (≥ 5 mg α-TE/day) were associated with reduced depressive symptoms. Energy, protein, and fiber intake also negatively correlated with depressive symptoms, emphasizing the importance of overall nutritional balance. Interestingly, Vitamin C intake was positively associated with anxiety symptoms, suggesting complex diet -mental health interactions. Implications for clinical practice highlight the importance of integrated nutritional screening and mental health interventions, particularly in underserved rural communities. However, given the observational nature of this study, further research is recommended to establish causality and explore the effectiveness of targeted supplementation programs.
