↵a Since the inclusion of covariates did not change the association of SDM with utilization, unadjusted results are shown.

↵b Rates are per 100 patients per year.

↵c

*P*values calculated from linear regression with robust variance estimation accounting for the MEPS complex survey design.↵d Rates are per patient per year.
