* P values were obtained by the Wald χ2 test for Poisson regression.
† Estimated mean return visit rates were calculated while holding covariates constant at their average values.
‡ Reference group is the 0% discount level.
§ Incidence rate ratio is for every 1-year increase in age.
‖ Reference group is men.
