Nutrient patterns and mortality: results from the Japan Multi-Institutional Collaborative Cohort (J-MICC) study.
Article in Nutrition journal, 2025. 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
backgroundThe consumption of a healthy diet may play an important role in the prevention of noncommunicable diseases (NCDs). Although associations between nutrient patterns and cardiometabolic risk factors or NCDs have been examined, the associations between nutrient patterns and mortality remain unknown. The present study examined the relationships between nutrient patterns and all-cause and cause-specific mortalities in a large Japanese population.
methodsA prospective cohort analysis was performed on the data of 72,939 participants aged 35-69 years with a mean follow-up of 11.7 years in the Japan Multi-Institutional Collaborative Cohort Study. A factor analysis was applied to the energy-adjusted intakes of 21 nutrients, and 4 nutrient patterns were extracted: Factor 1 (folate, carotene, fiber, vitamin C, potassium, iron, and retinol patterns); Factor 2 (unsaturated fatty acid and vitamin E patterns); Factor 3 (saturated fatty acid, calcium, vitamin B2 and low carbohydrate patterns); and Factor 4 (sodium, protein and vitamin D patterns). A multivariable Cox proportional hazards model was used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause and cause-specific mortalities according to the quartiles of nutrient patterns adjusted for potential confounders including age, sex, research site, drinking and smoking habits.
resultsDuring the follow-up period, 3,488 deaths were identified. A higher Factor 1 (folate, carotene, fiber, vitamin C, potassium, iron, and retinol) score was associated with lower all-cause (HR 0.81, 95% CI 0.73-0.90), CVD (HR 0.65, 95% CI 0.49-0.85) and cerebrovascular disease (HR 0.60, 95% CI 0.38-0.96) mortalities. The second lowest quartile group of the Factor 2 (unsaturated fatty acid and vitamin E) score was associated with lower all-cause (HR 0.86, 95% CI 0.79-0.94) and cancer (HR 0.85, 95% CI 0.76-0.95) mortalities. On the other hand, a higher Factor 2 score was associated with greater cerebrovascular disease mortality (HR 1.57, 95% CI 1.03-2.40).
conclusionsThe results of the present study suggest that increased adherence to nutrient patterns rich in folate, carotene, fiber, vitamin C, potassium, iron, and retinol or moderate adherence to unsaturated fatty acids and vitamin E are associated with a decreased risk of mortality in Japanese adults.
