Figure 2.

Comparison of "cumulative" survival rates of males and females after ozone-exposure followed by K. pneumoniae infection. Experimental design was described in the legend for Figure 1, and in the Methods section. Panel A: Data (in percent of control – FA) for differences in survival between males and females. Panel B: Graphic representation of area below the curve (O₃ and FA depicted by black and grey filled areas, respectively) of data shown in Panel A. The experiments from which these data are derived are in Panel B of Figure 1. The area below the curve was calculated with Sigma Plot 10.0 Software. O₃ (top) and FA (bottom) curves. The resulting ratios (O₃/FA times 100%) for males vs. females were compared with a t-test. Results were considered significant when p < 0.05, and are indicated with an asterisk, *.
