Abbreviations: CCP, Care Coordination Program; CI, confidence interval; NA, not applicable; RR, relative risk; VLS, viral load suppression.

^a Proportion with the last viral load result (≤200 copies/μL) in the 12 months prior to enrollment. Persons missing a viral load value are considered not to have suppression (values of >200 copies/μL).

^b Cannot compute the RR for persons with 0% viral load suppression. RRs were considered statistically significant when the 95% CIs for the relative risk excluded the null value of 1.

^c Excludes the newly diagnosed baseline viral load status group.

^d Newly diagnosed within 12 months of pseudoenrollment or enrollment.

^e Consistent suppression: at least 2 viral load results at least 90 days apart and all viral load values <200 copies/μL in the 12 months prior to pseudoenrollment or enrollment.

^f No evidence of viral suppression: All viral load values >200 copies/μL in the 12 months prior to pseudoenrollment or enrollment. This included persons missing viral load results. Persons with 1 viral load value of >200 copies/μL would be in this group.

^g Inconsistent suppression: previously diagnosed and not in the “consistent suppression” or “no evidence of viral suppression” groups. Persons with 1 viral load value of ≤200 copies/μL would be in this group.
