Cumulative incidence of fracture up to 18 months from R-CHOP1 according to risk group in the model derived from multivariate analysis of fracture risk factors. *Creating a simple score based on one point for each risk factor (score range, 0-3). One point for history of predisposing medical condition (known osteoporosis, osteopenia, RA, or prior fracture) regardless of use of bone-protective medication; one point for DLBCL bone involvement at baseline, regardless of whether associated with DLBCL-related fracture at baseline; and one point for use of prephase steroids.
