Comparisons of Radiographic Alveolar Bone Height [mean (SD)] Between Cases and Controls (N=66)^‡

	Unadjusted average (SD)		P-value for case vs. control
Characteristic	BRONJ (N=25)	Non-BRONJ (N=48)	Unadjusted Analysis	Adjusted Analysis 1†	Adjusted Analysis 2¶
Average bone height*	0.59 (0.06)	0.62 (0.03)	0.0041	0.0224	<0.0001
Fraction teeth bone height ≤ 0.50*	0.20 (0.23)	0.06 (0.09)	0.0013	0.0115	<0.0001

^‡Seven participants were excluded from the analysis: three were edentulous and four did not have bone height measures

^*Considering a maximum of 28 teeth, i.e., not counting 3rd molars

^†Adjusted for age, sex, and smoking status (ever vs. never)

^¶Adjusted for age, sex, smoking status (ever vs. never), and number of BP infusions (analyses excludes six BRONJ cases who received 60 or more infusions)
