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
Background: The Mediterranean and the Dietary Approaches to Stop Hypertension (DASH) diet are recognized for their cardiometabolic and preventive health benefits. However, the psychological and environmental determinants of adherence to these dietary patterns remain underexplored. The present study examined the direct and indirect effects of eco-anxiety, eco-awareness, and psychological distress on adherence to these healthy and sustainable diets. Methods: A cross-sectional online survey was conducted among 1,028 Turkish adults aged 18-65 years. Data were collected using validated instruments, including the Mediterranean Diet Adherence Screener (MEDAS), DASH-Questionnaire (DASH-Q), Depression Anxiety Stress Scale-21 (DASS-21), Hogg Eco-Anxiety Scale (HEAS), and the Awareness Scale for Reducing Ecological Footprint (ASREF). Statistical analyses included correlation tests, linear regression, and mediation models (PROCESS macro). Results: Linear regression analyses indicated that eco-anxiety significantly predicted higher adherence to both MEDAS [B = 0.329, 95% CI (0.101-0.557)] and DASH-Q [B = 1.409, 95% CI (0.234-2.585)], while eco-awareness predicted only DASH-Q [B = 2.289, 95% CI (1.719-2.859)]. Psychological models revealed that eco-anxiety strongly predicted depression, anxiety, and stress. Conversely, higher MEDAS [B = -0.157, 95% CI (0.279-0.034)] and DASH-Q scores [B = -0.027, 95% CI (0.051-0.003)] were associated with lower depression, while both also predicted lower anxiety. Mediation analyses confirmed significant negative indirect effects of depression and anxiety in the association between eco-anxiety and both MEDAS and DASH-Q, while stress mediated only the relationship between eco-anxiety and MEDAS. Notably, in all models the direct paths from eco-anxiety to dietary adherence remained positive. Conclusion: The results indicate a potential dual pattern in how eco-anxiety relates to dietary adherence. While eco-anxiety shows a positive association with adherence to healthy and sustainable diets, its connection with psychological distress is associated with lower adherence. Although these findings do not imply causality, they underscore the importance of considering both environmental concerns and psychological distress when examining determinants of dietary adherence.
