For example, a recent national study reported that approximately 160,000 more ciprofloxacin and 96,000 more doxycycline prescriptions were written in 2001 compared to 2000 [ 12].
This situation has been described in other studies; for example, in the first national survey in the USA, most patients experienced two or more hospitalizations before diagnosis [ 8].
Examples include situations where one requires local estimates of PAR for a study subset (e.g., in states or counties within a national study) or if one wishes to apply the findings of an epidemiologic study to another population.
Breast cancer incidence rates decreased by 2.2percentt annually from 1999 to 2005, for example, a drop some researchers attributed to large numbers of women quitting hormone replacement therapy after a national study linked it to breast cancer in 2002.
For example, the Million Women Study, a British study reported in 2003, showed that even estradiol and progesterone, which have been considered bioidentical hormones, increased the incidence of breast cancer; and Well-Hart, a national study reported in 2003, showed that estradiol did not prevent the progression of atherosclerosis.
For example, the national study used here estimated 17,909 PWID in London (13 ), but another study estimated >30,000 PWID in London for 2000 2001 (37 ).
For example, in our study, having a well-functioning AFS was both an outcome (at the local level) and a mechanism for further advancement in terms of the policies and programmes that sustain AFS (at the national level).
For example, in 2006 the national average population/doctor ratio was 138,000 persons per doctor, while the national average population/nurse ratio was 5,000 persons per nurse [ 11].
For example in media studies, students would have an unseen extract that they would analyse.
For example, in Ottawa, the Canadian national capital and site for this study, approximately 29% of people with type 2 diabetes receive all or part of their diabetes care from specialists [ 7].
