2 × 2 contingency table for rapid MALDI-TOF MS identification as index test compared to bacterial culture as reference test for identification of respiratory pathogens in pure and dominant BALf culture samples of cattle.

Pure and dominant cultures only	Bacterial culture +	Bacterial culture −a	Total
Rapid MALDI-TOF MS+	23	0	23
Rapid MALDI-TOF MS−	15	34	49
Total	38	34	72

^aAll polymicrobial and negative cultures. When MALDI-TOF MS identified a contaminant, the result was considered rapid MALDI-TOF MS−.
