a. The following variables were also tested as potential predictors but were not found to be significant at either the univariate or multivariate level: place of residence (urban or regional), ever having had an STI test, know that a pap smear cannot diagnose all of the main STIs, know that chlamydia can be diagnosed using a simple urine test, and having a new partner in the past three months.
b. Grouped data do not always add up to the total number of participants (902) who opted to receive a chlamydia testing kit due to non-responses.
c. Hosmer-Lemeshow: p = 0.60
d. Inconsistent condom use was defined as not always using condoms with new and/or casual partners, and/or regular partners if multiple regular partners were reported within the last year.
e. Hazardous drinking was defined as drinking more than six alcoholic drinks in a session at least weekly.
