Engagement in Care	N	Percent Engaged	N	Percent Engaged	p-value
6 months	39	87.2	59	93.2	0.48
12 months	38	73.7	27	88.9	0.21

Table 3 shows the observed outcomes by level of PL use. PL members are included in a given time point for which they were actively enrolled in PL, defined as receiving daily queries for at least 5.5 months of the 6-month interval. Members who responded to ≥48% of daily queries in the prior 6-months are classified as high PL users; those with <48% response rates are low users. Viral suppression is defined as having a viral load <200 copies/mL. Engagement in care is defined as having attended 2 or more HIV appointments separated by at least 90 days within the past year.
