For BP outcomes at the end of the 12-month intervention, we selected 1 BP reading from 0 to 15 months, but closest to 12 months after enrollment; for 24-month postenrollment follow-up, we selected 1 BP reading from 0 to 27 months, but closest to 24 months after enrollment; and for 48-month postenrollment follow-up, we selected 1 BP reading from 0 to 51 months, but closest to 48 months after enrollment. The 95% CIs and ORs account for clustering by physician using generalized linear mixed models. P values correspond to a Wald-based F test with denominator degrees of freedom estimated using the containment method.
