Total time was extracted from the fully adjusted model in Table 2. Those models were adjusted for protein intake, age, sex, education, energy intake, Standardised Mini-Mental State Examination Score, number of chronic diseases, and physical activity. Participant numbers are from the baseline assessment. One participant (n = 1) did not have physical assessment
