B is the coefficient each time.
The dependent variable is the hospital performance score; **p<0.01, ***p<0.001.
Model 1 adjusted for manager type.
Model 2 adjusted for variables of model 1 with additional adjustment for COO’s tenure.
Model 3 adjusted for variables of model 2 and hospital type.
Model 4 adjusted for variables of model 3 with additional adjustment for ownership.
