All values represented are means ± standard deviation or count (%)

p-values within PASE quartiles represent significance of change from baseline to follow-up.

p-values represent overall test of difference in means between PASE quartiles

P-values represent differences in change from baseline to follow-up between PASE quartiles

PASE – Physical Activity Score for the Elderly
