The Effects of Trends in Osteoporosis Treatment on the Incidence of Fractures

Table 5

Comparisons of the incidence of fracture: oral vs. IV/SC group, oral vs. IV/Bis group, and oral vs. anabolic group.

	Oral group	IV/SC group	RRR	CI
Fracture number	32 (2.4%)	4 (1.1%)	0.559	−0.183–0.837
(Total number)	(1337)	(379)
	Oral group	IV/bis group	RRR	CI
Fracture number	32 (2.4%)	4 (2.3%)	0.021	−1.264–0.615
(Total number)	(1337)	(171)
	Oral group	Anabolic group	RRR	CI
Fracture number	32 (2.4%)	0 (0%)	1.000	0.219–1.000
(Total number)	(1337)	(208)

IV/SC: intravenous/subcutaneous, RRR: relative risk reduction, CI: confidence interval IV/bis: intravenous bisphosphonate, RRR: relative risk reduction, CI: confidence interval IV/SC: intravenous/subcutaneous, RRR: relative risk reduction, CI: confidence interval.
