From: Variability of anti-staphylococcal antibodies in healthy volunteers and pre-cardiac surgery patients
Categorised antibody response (positive, weakly positive, negative) to alpha-toxin and teichoic acid domains in healthy volunteers (HV), n = 25, and in pre-operative cardiac surgical patients (PS), n = 25. Fisher’s exact test (Freeman-Halton extension) used to test variability of response between groups
