Association of micronutrient levels with dementia risk in adults in Telangana, India: a cross-sectional study (2023-2024).
Article in The Lancet regional health. Southeast Asia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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: Dementia develops from a complex interplay of genetic and environmental factors, and nearly half of dementia globally are attributable to modifiable risk factors, including nutrition. We aim to examine the relationship between nutritional status and dementia risk factor burden, as quantified by the context-specific CAIDE score, for its applicability in India. Methods: This community-based cross-sectional study involved middle-aged and older-adults residing in Telangana, India. The Indian-specific CAIDE score was calculated using the variables: age, gender, education, BMI, physical activity, systolic blood pressure, and total cholesterol. Dietary intake and blood vitamin levels were estimated and correlated with the dementia risk factor burden. Findings: Among 556 study participants (mean age: 63 years), 39% had a predicted risk of dementia (≥9 CAIDE score). The risk was higher in rural areas (60% vs 27%) and in females (55% vs 45%). Vitamin B2 deficiency was most prevalent (64%), followed by vitamin D (42%), B6 (34%), active B12 (17%), B9 (8%), and B1 (3%). The prevalence of deficiencies in vitamin D, B2, B6, and B9 was significantly higher in the high-risk group (HRG) than in the low-risk group (LRG). Dietary diversity was lower in the HRG than in the LRG. Saturated fat intake was higher, whereas unsaturated fat intake was lower in HRG than in LRG. Vitamin deficiencies (D, B2, B6, B9, B12) were significantly higher among rural participants than among urban participants. Interpretation: This study applies a context-specific CAIDE score for dementia risk assessment in adults from India and reports its association with nutritional markers.
