Percentage of epochs with significant responsiveness (rows) to change in step count across different wear time durations (columns).

Follow-up period	1 day	2 days	3 days	4 days	5 days	6 days
6 months (n = 5)	0	20	40	20	20	20
12 months (n = 4)	50	75	75	50	75	50
18 months (n = 3)	100	66.7	100	66.7	100	66.7
24 months (n = 2)	100	100	100	100	100	100
30 months (n = 1)	100	100	100	100	100	100
Mean progression detection rate (%)	70.0	72.3	83.0	67.3	79.0	67.3

Note: The n-numbers in the first column refer to the number of possible epochs of a certain duration – see Figure 3. The mean progression detection rate (bottom row) is the average across all 15 epochs.
