Mean (+/− standard error) values are displayed for burst activity (MFI) and % of cells undergoing burst response.
R = Responders; NR = Non-Responders; MFI = mean fluorescence intensity; Mac = macrophages; PMN = Polymorphonuclear neutrophil; ns = not significant.
* Ozone Response values were calculated as the mean of the sum of the individual subject differences in oxyburst values between post and pre exposure.
pre = 48 hours pre exposure; post = 5 hours post exposure.
