REGRESSION
A mixed ANOVA (repeated measure) was performed to check if there was any significant difference in the average knowledge/adherence across different time points as well as between the intervention group and the control group. A nonparametric approach of mixed ANOVA is performed using the R package “nparLD” to check if there was any significant difference in the average adherence/QoL across different time points as well as between the intervention group and control group as data violated the normality assumptions. As the outcome variable “Knowledge” was not normally distributed, quantile regression was used to determine the factors related to this outcome. As the outcome variable “Adherence” was not normally distributed, quantile regression was used to determine the factors related to this outcome.
