Notes: Only one independent variable made a unique statistically significant contribution: the relationship between subjective VA improvement (as perceived by the patient after receiving three loading doses) and objective compliance (as set by aforementioned criteria) was statistically significant, X2 (1, N = 117) = 4.540, p =0.033, V =0.197.
