Association between nutrition knowledge and Mediterranean diet adherence in Israeli adults with type 2 diabetes.

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
objectivesTo investigate the association between dietary knowledge and adherence to Mediterranean diet (MedD) among people with type 2 diabetes (T2D) in Israel.
methodsIn this cross-sectional single-center study, adults with T2D visiting a diabetes clinic were enrolled for an interviewer-administered survey. Dietary knowledge was assessed using a questionnaire adapted for locally available foods. MedD adherence was measured using the Israeli Mediterranean Diet Adherence Screener (I-MEDAS). Additional clinical and anthropometric characteristics were retrieved from patients' medical records. The association between dietary knowledge and MedD adherence was analyzed in a multivariable logistic model. RESULTSF: A total of 134 people were included. Mean age was 70 ± 10.7 years; 54.5% were women. The mean dietary knowledge score was 12.1 ± 2.4 (range: 0-17), and the MedD adherence score was 11.0 ± 2.1 (range: 0-17). In multivariable analysis, adjusted for age, sex, socio-economic status and diabetes duration, people in the highest tertile of dietary knowledge were more likely to be in the highest tertile of MedD adherence (adjusted odds ratio 4.6, 95% CI 1.5-14.8, p = 0.01), compared to those in the lowest knowledge tertile. The model explained limited variance in adherence (Nagelkerke R² = 0.16). Sensitivity analyses using the exposure and outcome variables as continuous scores were not statistically significant.
conclusionDietary knowledge showed a modest association with MedD adherence in Israeli adults with type 2 diabetes, but this association lacked robustness across analytical approaches. Dietary knowledge explains a small proportion of dietary adherence variability, suggesting that unmeasured factors play a more substantial role in determining dietary behavior.
