Association of midlife macronutrient and mineral intake with subjective cognitive complaints in a prospective cohort of women.
Article in European journal of nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeFew studies have examined the association between dietary nutrients and subjective cognitive complaints (SCCs), which are potential predictors of Alzheimer's disease-related dementia (ADRD). We aimed to examine the association of midlife intake of macronutrients, as well as of a few other nutrients, with SCC development.
methodsWe included 5119 participants who responded to the 2018 or 2020 follow-up questionnaire of the New York University Women's Health Study. Dietary data were collected using a validated self-administered Block food frequency questionnaire, and nutrient intake were calculated using food lists and food composition tables. SCCs were assessed using a standardized questionnaire.
resultsDietary intakes of fiber, carbohydrates, and potassium were inversely associated with having ≥ 2 SCC (p-trend = 0.0047, 0.026, and 0.0015, respectively), whereas higher intakes of total fat and saturated fat, as well as a higher ratio of fat to carbohydrates, were positively associated with ≥ 2 SCCs (p-trend = < 0.0001, 0.0015, and 0.0025, respectively). The positive associations of total fat intake and the log-ratio of fat to carbohydrates with ≥ 2 SCCs remained significant after controlling for other nutrients (p-trend = 0.008 and 0.036, respectively). The association between total fat intake and SCCs was stronger among participants with lower caloric intake (< median = 1430 kcal) compared with those consuming higher intake (≥ 1430 kcal) (p-value for interaction = 0.0049). The associations did not differ appreciably by other factors.
conclusionWe observed a positive association between midlife dietary fat intakes and SCCs in later life in a cohort of women.
