  1. 1Accounted for repeated measures from individuals GPs; 2The multivariable models have adjusted for patient gender; 3Answers were classified as correct if they ticked at least one correct answer - 15-19 and 20-24 year olds; 4Answers were classified as correct if they ticked at least one correct answer - 20-24 and 25-29 year olds; 5Knowledge of population groups to be targeted for screening is one point for correctly offering a test under the 2010 RACGP guidelines - tests should be offered to cases 1, 2, 4, 5, 7 & 8 but not offered to cases 3 & 6; 6Azithromycin is the correct treatment for men, women and pregnant women; 7RACGP guidelines recommend re-testing every 12 months after a negative test and every 3 months after a positive test; 8Correct signs and symptoms suggestive of PID are tenderness with motion of the cervix, adnexal tenderness, uterine tenderness, lower abdominal tenderness and inflamed cervix; 9Correct diagnostic tests are pregnancy test, chlamydia and gonorrhoea test, abdominal palpation and bimanual examination.
