The following significance values are used: †p<0.10; *p<0.05; **p<0.01.
ηp2 refers to the degree to which variability among observations can be attributed to conditions controlling for the subjects’ effect that is unaccounted for by the model.
Df for the time x group interaction=1 for all study variables and 111 for the error(time).
