Ordinary least squares regression using log reimbursement cost as the outcome variable. Coefficients should be interpreted as the percentage change in reimbursement cost associated with a one unit increase in the value of the explanatory variable.
*P<0.05; **p<0.01; only variables that were significant at the 5% significance level are included.
CRT-D, cardiac resynchronisation defibrillator; ICD, implantable cardioverter-defibrillator.
