r
Standard errors for the underserved sample are corrected for physician-level clustering. Standard errors for the MEPS data are corrected for complex survey sampling.
s
Trial data gathered at baseline for prior 3 months only. The data are converted to an annual measure by assuming that the annual usage rate is 4 times the prior 3-month rate.
t
The majority of the urban sample is of Latino descent while the majority of the nonurban sample is white and non-Latino.
