The effect of Mediterranean Diet adherence on the relationship between cognitive performance and cancer survivorship.
Article in Journal of cancer survivorship : research and practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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/
objectivesUp to 75% of cancer survivors experience cognitive impairment from cancer or its treatment. No modifiable risk factor has been identified; however, a Mediterranean Diet may be protective. We sought to determine if the relationship between cognitive performance and cancer survivorship depends on Mediterranean Diet adherence.
methodsWe used the latest data from the National Health and Nutrition Examination Survey (NHANES). Mediterranean Diet adherence was defined as the aMed score which gives 1 point for intake above/below the sample-specific median for healthful/unhealthful food groups (range 0-9). Cognitive processes assessed included processing speed, attention, working memory, learning, short-term memory, and executive function. Linear regression models adjusting for demographics, diet, and health behavior were used to determine the relationship between cognition and cancer history.
resultsAmong 2450 participants, 385 had cancer. Mean age was 68.9 years (SE = 0.2). The most common cancer was breast cancer (24%). Cancer history was not associated with cognition (p > 0.05). Among high aMed scores, cancer history was more negatively associated with number of Intrusions compared to low aMed scores (β (95% CI): 0.61 (0.07, 1.16), p = 0.03 for aMed*Cancer interaction term).
conclusionsCancer history was more negatively associated with cognition among high versus low aMed scores. Because of the cross-sectional nature of NHANES, the limited number of cancer survivors, and the lack of treatment information, larger prospective studies with treatment data are needed. IMPLICATIONS FOR CANCER SURVIVORS: Cancer survivors may require dietary recommendations different from that of the general population. More studies, however, are needed to confirm this.
