1. Kaplan-Meier survival rates for linezolid vs vancomycin were 80.0% (60 of 75 patients) vs 63.5% (54 of 85 patients) for the MRSA subset (p =0.03).

2. Clinical cure rates for linezolid vs vancomycin (excluding indeterminate or missing outcomes) were 59.0% (36 of 61 patients) vs 35.5% (22 of 62 patients) for the MRSA subset (p < 0.01).

The model estimated a higher clinical cure (+8.7%) and survival (+13.2%) for linezolid compared with vancomycin at an incremental cost of €420 per treatment episode. The cost–benefit profile suggests that linezolid could be considered a cost-effective alternative to vancomycin in the treatment of patients with NP caused by suspected MRSA in Germany.
