Failure to do so as a result of violating principles of a regression model will call for a subgroup analysis, where a student t test will be used for the comparison between the subgroups.

It is also planned to study the interactions between the variables via ANOVA test if the data show normal distribution.

Participants with missing data will be excluded.
