  1. Results of multivariate logistic regression analysis with dietary habits and RA-related factors regarding the presence of prefrailty or frailty. Model was adjusted for age, RA duration, RA therapeutics (use of prednisolone, biologics and methotrexate), DAS28-ESR, and dietary habits (only fish dish (model 1), fish + meat dishes (model 2) and fish/meat/milk/vegetable/fruits (model 3) as variables).
  2. Dummy variables were constructed for intake frequency as 0 and 1: Fish and Meat dish: 0 = low frequency (≤ 2 times/weeks), 1 = high frequency (3 times/week ≤) and Milk, Vegetable and Fruits: 0 = low frequency (≤ 6 times/week), 1 = high frequency (1 time/day ≤).
  3. RA rheumatoid arthritis, DAS28-ESR 28-joint Disease Activity Score using erythrocyte sedimentation rate, MTX methotrexate, PSL prednisolone.
