Association of Vitamin E Intake with All-Cause Mortality Among Individuals with Rheumatoid Arthritis: A Cohort Study from the NHANES 1999-2018.

Background: The relationship between dietary vitamin E intake and mortality rates among rheumatoid arthritis (RA) patients remains a relatively uncharted territory in nutritional epidemiology, underscoring an important gap in research.

Objectives: This study is to explore the potential association between dietary vitamin E intake and all-cause mortality in the RA patient population.

Methods: This longitudinal cohort study analyzed 2,906 RA patients aged 20 years or older who participated in the National Health and Nutrition Examination Survey from 1999 to 2018.
