Model 1: crude mixed-effects model

Model 2: mixed-effects model adjusted for baseline skill

Model 3: mixed-effects model adjusted for baseline skill, TPB, and knowledge, gender, and age

Model 4: mixed-effects model adjusted for baseline skill, TPB, and knowledge, gender, age, ethnicity, position, job title, and years of experience

Test for the effect of intervention by province in the overall analysis produced a p-value of 0.007 after adjusting for baseline skill, TPB, and knowledge, gender, age, ethnicity, position, job title, and years of experience
