Adjusted P-values represent P-values for the treatment group (IMN vs. ORIF) parameter estimate from a multiple linear regression model for the corresponding outcome variable, controlling for patient sex, age, BMI, comorbidities (smoking, diabetes, osteoarthritis), initial joint line displacement, and initial condylar widening.
