Sex differences in the effect of ozone exposure on survival rates of SP-A (-/-) mice afterK. pneumoniaeinfection. Experimental design was performed as described in the legend for Figure 1. In this analysis, males and females were analyzed separately to compare the effect of ozone on the survival of infected mice of different sex. Significant differences by log-rank test (cumulative survival, for all 14 days): #FA group of SP-A (-/-) or WT mice vs. the corresponding ozone group. Significant differences by Fisher's exact test (daily survival): as above for cumulative survival, but for daily analysis each asterisk (*) corresponds to significant differences for the respective day located above. Data for WT mice shown by the dotted line are from Mikerov et al. .
