p-values from basic model;

2

p-values from analysis of covariance adjusted for age and sex.

Note that the distribution of physical activity, creatine kinase, white blood cell, reticulocytes, myocardial infarction, diabetes, cancer, angina, stroke, transitory ischemic attack, atrial fibrilation, congestive heart failure, chronic renal insufficiency, hypertension, rheumatic arthritis and osteoarthritis, were substantially similar between groups (adjusted p-value >0.3) and therefore they are not represented in this table.
