  1. *β represents unadjusted monthly change in percent data concordance through use of a linear mixed model with random intercepts for clinics and random slopes over time. A linear spline was used to model time with knots at 12 (January 2010), 24 (January 2011), and 36 (January 2012) months of data collection.
