  1. SD Standard deviation. † When the one-way analysis of variance was significant (p < 0.05), pairwise post hoc comparisons were conducted using Fisher’s least significant difference (LSD) test. Different letters (a, b and c) denote that adherence was significantly different (p < 0.05), and the same letters denote that adherence was not significantly different
