BMI, body mass index.
Standardized β and odds ratios are calculated per SD change.
A negative beta coefficient (β) indicates that odds of treatment response increases with a reduction in the input variable (e.g. odds of treatment response increases with lower event depth, age, and BMI).
Adjusting each model for study site had no impact on the statistical significance or strength of the associations of the predictor variables with oral appliance treatment response.
