Adjusted Healthy Eating Index (HEI) data in a subset of 122 oldest-old participants from the Geisinger Rural Aging Study according to perceived physical fatigability status: Pittsburgh Fatigability Scale (PFS).

Data are covariate-adjusted mean ± SE. Covariates included age group, sex, BMI, and total number of medical conditions. p-values for mean differences in the individual HEI scores between fatigability categories after adjusting for covariates.
