1 · What the graph read from it

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.

2 · The registry

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

backgroundThis study aimed to examine the validity and reliability of the Chrono-Med Diet Score (CMDS) to assess adherence to the Mediterranean diet in Turkish adults.

methodsThe methodological research conducted in Gümüşhane and Ordu from January to June 2024, including 592 individuals (62.3% women, 37.7% men, and the mean age 43.4 ± 10.6 years). Data were collected through face‒to‒face interview that contained socio-demographic characteristics, the CMDS, the Mediterranean Diet Adherence Screener (MEDAS), and 24-h dietary recall. Internal consistency reliability was assessed using Cronbach's alpha coefficient, while repeatability was examined using the test-retest method. Construct validity was assessed by the MEDAS, and components of the adapted CMDS obtained from the 24-h dietary recall were analyzed using confirmatory factor analysis. The content validity was assessed by the Paired samples t-test and Wilcoxon test. The Bland-Altman test with 95% limits of agreement was used to evaluate the agreement between sum of CMDS. The results were statistically evaluated at a p < 0.05 significance level.

resultsThe content validity index of CMDS was 0.87. The overall Turkish version of CMDS had acceptable internal consistency (Cronbach's α = 0.853), thus indicating that the score was reliable. The Paired samples t test coefficients between each item and the overall questionnaire ranged from 0.234 to 1.000. A higher intake of olive oil and fish obtained from a 24-h dietary recall was associated with a higher CMDS quartile (p < 0.05). The MEDAS score was correlated with a higher CMDS quartile (p < 0.001). A moderate positive correlation was determined between total CMDS and MEDAS (r = 0.467; p < 0.001).

conclusionsOur assessments of the CMDS, consisting of 13 items, in Türkiye demonstrate that it is a viable and reliable instrument to measure adherence to the Mediterranean diet for the adult population. The CMDS is more accurate than other Mediterranean diet scores as it questions about the amount of physical activity and grain products, which helps determine each participant's eating patterns and general health.
