Association between plant-based diets and depressive symptoms among Chinese middle-aged and older adults.

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 aimed to evaluate associations between plant-based diets and the prevalence of depressive symptoms (DepS) among Chinese middle-aged and older adults. This study included 3153 participants aged 45 and older. Dietary intake was collected using a food frequency questionnaire, and DepS was evaluated using the 9-item Patient Health Questionnaire. Foods were classified into 17 groups and three plant-based diet indices were created, including the overall plant-based diet index (PDI), healthful plant-based diet index (hPDI), and unhealthful plant-based diet index (uPDI). Compared to the lowest quartile, participants in the highest quartile of hPDI had lower odds of DepS (OR = 0.60; 95% CI: 0.40, 0.89). Conversely, the highest quartile of the uPDI was associated with higher odds of DepS (OR = 1.81; 95% CI: 1.16, 2.82). These findings supported that the quality of plant-based diets matters for mental health.
