Depressive symptoms, oral health behaviors, and self-reported oral health conditions among Chinese university students: a cross-sectional study.

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
Introduction: Depression has been associated with adverse oral health behaviors and conditions, but the mechanisms underlying these associations remain incompletely understood, particularly the potential role of oral health behaviors. This study examined these associations of depressive symptoms with oral health behaviors and self-reported oral health and explored statistical indirect associations through oral health behaviors among Chinese university students. Methods: This cross-sectional study included 2,695 undergraduate students from seven universities in Shandong, China. Data were collected using an online questionnaire. Depressive symptoms were assessed using the 10-item Center for Epidemiologic Studies Depression Scale (CESD-10). Oral health was self-reported and included self-rated oral health and six predefined oral health problems, including dental caries, gingival bleeding, oral ulcers, tooth sensitivity, oral malodor, and other periodontal-related problems. Ten favorable oral health behaviors were summarized using an unweighted composite score. Multivariable linear, multinomial logistic, negative binomial, and binary logistic regression models were used as appropriate. Exploratory mediation analyses with 5,000 bootstrap resamples assessed statistical indirect associations through oral health behaviors. Results: Higher CESD-10 scores were associated with poorer oral health behaviors and worse self-reported oral health. Each 1-point increase in CESD-10 score was associated with a lower oral health behavior score ( Conclusion: Depressive symptoms were associated with poorer oral health behaviors, worse self-rated oral health, and a greater burden of self-reported oral health problems among university students. Oral health behaviors explained a modest proportion of these statistical associations. These findings support further investigation of integrated mental and oral health promotion strategies in university populations.
