Choice Method	28.3	21.1	5.3	1.42 (1.05, 1.92)	.022

Note. N = 193 patients. Duration at clinic is measured in weeks. NPT = received non-preferred treatment; PT = received preferred treatment. Non-preferred treatment is defined as any treatment in the bottom 25% of a given patient’s preference rankings; preferred treatment is defined as any treatment in the top 75% of preference rankings.
