  1. Sites completed observations on average 4.0 days per site at baseline and 4.3 days per site at follow up. Baseline and follow up means represent site-level averages
  2. aNumber of OSNAP goals met per day, out of 9 possible
  3. bDifference in change in aggregate healthy practice score between intervention and control arms. Estimated among all observation days within sites, using linear mixed regression models accounting for clustering of days within sites using a compound symmetry variance-covariance matrix and between-within method of estimating denominator degrees of freedom
  4. cOdds ratio for difference in change in percent of days meeting goal between intervention and control arms. Estimated among all observation days within sites, using generalized linear regression models with a binomial distribution and logit link, accounting for clustering of days within sites using a compound symmetry variance-covariance matrix
  5. dN/A indicates not applicable because models did not converge due to small numbers of sites not meeting goals
