a P value for comparison of all three activity groups (low, medium, and high).

b Post hoc 2-sample Wilcoxon rank-sum test values: low versus medium activity groups (P=.05), low versus high activity groups (P=.01), and medium versus high activity groups (P=.22).

c Post hoc 2-sample Wilcoxon rank-sum values: low versus medium activity groups (P=.01), low versus high activity groups (P=.003), and medium versus high activity groups (P=.21).

d P value for correlation between termination of step counter use and mean steps walked at the specified days.

e ACS: acute coronary syndrome.
