a

Number of participants detected with an incident chlamydial or gonococcal infection at the 6-, 12-, 18-, 24-, 30-, or 36-month assessment (therefore, total comparison participants with ≥1 follow-up included in analyses, n = 318; total experimental participants with ≥1 follow-up included in analyses, n = 309).

b

Biological outcome adjusted by baseline variables: clinic, family aid index (receipt of government assistance), years in school, partner communication frequency, unprotected vaginal sex in the past 90 days, history of emotional and physical abuse, depression, perceived partner concurrency, corresponding baseline result, and dose of telephone contacts.
