Notes: This table shows the bivariate relationships between the guideline-defined indicators for recommended follow-up frequency, as well as “Cowboy” and “Comforter” status among both PCPs and cardiologists in the (restricted) analysis sample. χ2-tests evaluate the null hypothesis that there is no association between pairs of indicators in the table.
