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
objectiveIn the digital age, the ability to critically evaluate online nutritional information is of paramount importance. This study aimed to examine the relationships between digital healthy diet literacy (DHDL), attitudes towards artificial intelligence (AI), adherence to the Mediterranean Diet (MD), and the physical and mental components of health-related quality of life in adults.
methodsThis cross-sectional study was conducted in Ankara, Turkey, using snowball sampling and a web-based questionnaire; 1240 adults (740 women, 500 men) aged 18–65 were included in the study. Data were collected through a web-based questionnaire that included demographic information, self-reported anthropometric measurements, and validated scales. The scales used include: Digital Eating Literacy Scale, Attitudes toward Artificial Intelligence Scale, Short Form-12 Quality of Life Scale (SF-12), and Mediterranean Diet Adherence Scale (MEDAS).
resultsDHDL scores showed significant positive correlations with AI attitude scores (r = 0.195), the physical (r = 0.218) and mental (r = 0.291) components of health-related quality of life, and MD adherence (r = 0.206) (p < 0.001 for all). Similarly, higher attitudes toward AI were significantly associated with better MD adherence (r = 0.250) and higher physical (r = 0.138) and mental (r = 0.129) quality of life. Linear regression analyses indicated that demographic and socioeconomic factors such as gender, age, marital status, education and income level, and employment status were significant predictors of digital healthy diet literacy (DHDL), AI attitudes, Physical Component Summary-12 (PCS-12), Mental Component Summary-12 (MCS-12), and MEDAS scores (p < 0.05).
conclusionsHigh DHDL levels, positive attitudes toward AI, and high adherence with MD are interrelated and positively correlated with better health-related quality of life. In public health strategies, incorporating holistic interventions that improve DHDL, encourage positive interaction with AI-based health tools, and support adherence to evidence-based dietary patterns such as the MD may contribute to improved overall well-being.
