Results obtained from a multivariable logistic regression model for CIED infection based on all the variables listed in the table.
AICD = automatic implantable cardioverter-defibrillator; CI = confidence interval; CIED = cardiovascular implantable electronic device; CoNS = coagulase-negative Staphylococcus; CRT = cardiac resynchronization therapy; ESRD = end-stage renal disease; GPC = gram-positive cocci; SA = Staphylococcus aureus; VGS = viridans group streptococci.
