However, when comparing the intention-to-treat approach with the per-protocol analysis, slightly differing results emerged (ITT: significant main effects of interactions between footbath condition and time ( F (4, 317) = 2.96, p =0.02) and between health status and time ( F (2, 317) = 3.65, p =0.03); PP: both interactions were only marginally significant (footbath condition x time: F (2, 277) = 2.31, p =0.06; health status × time: F (2, 277) = 3.02, p =0.05)). 3.7.
