Absolute rate increases were similar for the implant (9.0\/1000) and IUS (10.8\/1000), with increases observed across all age groups and states\/territories. Overall dispensing rates varied by two\u2010fold according to state\/territory of dispensing and four\u2010fold according to age groups. Rate increases for the implant were highest among the 15\u201319 and 20\u201324 age groups, while rate increases for the IUS were highest among the 35\u201339 and 40\u201344 age groups.
