Sensitivity for MRSA infection and number of patients with risk factors. Sensitivity for MRSA infection is plotted according to the number of patients with at least one of the four independent risk factors identified in the present study. A closed circle indicates sensitivity and number of patients with at least one of the 4 factors, an open circle indicates sensitivity and number of patients with at least one of 3 factors, an open square indicates sensitivity and number of patients with at least one of 2 factors, and a closed triangle indicates sensitivity and number of patients with only 1 factor. The combinations circumscribed by the ellipse were the best subset of a small group of patients with the highest sensitivity for MRSA infection. MRSA: methicillin-resistant Staphylococcus aureus; INT: intubation; OW: open wound; TA: treatment with antibiotics; ST: steroid administration.
