Sensitivity analyses using several measurements of continuity of care. (A) Analysis of the association between continuity of care (COC) and risk of major osteoporotic fracture (MOF) by classifying the COC index into four categories. (B) Analysis of association between COC and risk of MOF by different cut-offs in COC index and usual provider of care (UPC). UPC = Nu/N; where N is the total number of outpatient visits and Nu is the number of visits to routine health care providers. COC continuity of care, MOF major osteoporotic fracture, UPC usual provider of care.
