  1. Time 1 = pre-the Women’s Health Initiative (WHI) 2002 study (1996 – 9 July 2002), Time 2 = post-WHI 2002 (10 July – 19 September 2002), Time 3 = September 2002 – June 2010, HT = hormone therapy, HM = herbal medicine, SD = standard deviation, ARIA = Accessibility Remoteness Index of Australia
  2. Aonly two calls asking about hormone therapy and herbal medicines in Time 2
  3. bSome calls from Queensland Medication Helpline have more than one question recorded. The proportion in this variable reflects the proportion of the number of enquiry type to total enquiry type (Time 1, number of questions (n) HT only = 1,547, HT and HM = 63, HM only = 129; Time 2, n HT and HM = 170)
  4. cRelative call frequency was calculated by dividing the proportion of calls by the proportion of population in the specific ARIA index
