Relationships among mediterranean diet adherence, sustainable food literacy, and depression in healthcare professionals.

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
backgroundThe Mediterranean diet has been linked to beneficial physical and mental health outcomes, whereas sustainable food literacy supports environmentally responsible and health-conscious eating behaviors. Healthcare professionals, owing to their societal role, are a critical group for promoting these practices.
objectivesThis study aimed to examine the relationships among Mediterranean diet adherence, sustainable food literacy, and depression levels among healthcare workers and to explore their associations with demographic and lifestyle factors.
methodsA cross-sectional study was conducted with 251 healthcare workers. Data were collected via the Mediterranean Diet Adherence Screener (MEDAS), the Sustainable Food Literacy Scale, and the Beck Depression Inventory. Statistical analyses included correlation and regression models.
resultsCompared with men, women scored higher on the sustainable food literacy subdimension. Nonsmokers demonstrated greater adherence to the Mediterranean diet, whereas individuals with chronic diseases had higher depression scores. Individuals with chronic diseases reported higher depression levels. The lowest adherence rates within the MEDAS items were observed for wine, fish and seafood, and fruit consumption, whereas the highest adherence was found for using tomato–garlic–onion sauces and preferring white over red meat. The participants with minimal depression reported significantly higher MEDAS and food literacy (knowledge subscale) scores than did those with severe depression. MEDAS scores were positively correlated with sustainable food literacy and negatively correlated with body mass index. Regression analysis indicated that depression negatively predicted both the MEDAS score and the sustainable food literacy score.
conclusionsThe findings emphasize the interconnectedness of adherence to the Mediterranean diet◊, sustainable food literacy, and mental health among healthcare professionals. Integrating nutrition education and promoting the Mediterranean diet may enhance psychological well-being while fostering sustainable eating behaviours. Future research should expand to diverse professional groups and evaluate the impact of targeted interventions.
