Table 2.
Physical activity levels and dietary intake in participants based on thymic scores. Physical activity is based on accelerometer-derived data, and calculated nutrients/day of energy, macronutrients, fiber and micronutrients are based on the food frequency questionnaire MiniMeal-Q. Four groups of thymic scores are presented; Score 0, complete fatty replacement, no identifiable soft tissue in the thymic bed, Score 1, predominantly fatty thymus, Score 2, approximately one-half fatty and one-half soft tissue attenuation thymus, and Score 3, predominantly soft tissue attenuation thymus
