Effectiveness of antimicrobial coverage relative to gram positive coverage alone in reducing infection risk in long-bone reconstruction

Antimicrobial Coverage	Definitely less effective than Gram + alone	Moderately less effective than Gram + alone	Equivalent to Gram + alone	Moderately more effective than Gram + alone	Definitely more effective than Gram + alone
Gram + and Gram - coverage	2 (3.0%)	2 (3.0%)	33 (50.0%)	23 (34.8%)	6 (9.1%)
Gram - coverage alone	40 (60.6%)	16 (24.2%)	10 (15.2%)	0 (0.0%)	0 (0.0%)
Vancomycin	3 (4.6%)	6 (9.2%)	31 (47.7%)	22 (33.8%)	3 (4.6%)
