Analysis of covariance for log-transformed 6-minute walk data controlling for baseline scores and treatment fidelity

Effect	F statistic
Group	5.59*
Baseline score	34.36*
Treatment fidelity	3.98†

^*Significant at p = 0.01 or better;

^†significant at p = 0.05 or better.

Subsequent pairwise comparisons showed significant differences between the conversation group and both the walking group (p < 0.05) and (he combined treatment group (p < 0.01).
