^#Outcomes of tests determined at 9 months after date of initial test; In 5 tests no outcomes could be determined because the patient did not return to the institution after the initial test.

^{^}Numbers will not add up to 92 or 100% as more than one outcome was possible for a unique patient.

^ŦIn 6 patients a new diagnosis had not yet been established by the time of review because work-up was still in progress.
