Individual risk patterns for a random sample of 5 HIV-negative Multicenter AIDS Cohort Study (MACS) participants with ≥8 study visits from each of the identified sexual risk trajectory groups: low risk, moderate risk, and high risk. Blue lines indicate no or low risk 6-month intervals between study visits with an SRB score<4. Red lines indicate high risk 6-month intervals between study visits with an SRB score ≥4. Blank intervals indicate a missed visit at the end of the 6-month interval, thus data on the risk behaviors practiced during the interval were not obtained.
