BALF injury markers. a. pH of BALF. Mean ± SEM. 3-way ANOVA, EHC-93, p = 0.048 and Ozone × Recovery, p < 0.001. Tukey, *0 vs 50 mg/m3 EHC-93, †0 h vs 24 h within 0.8 ppm O3, ‡0 h vs 24 h within 0 ppm O3, p < 0.05. 2-way ANOVA, Ozone, p < 0.001. Tukey, #0 and 0.4 vs 0.8 ppm O3, p < 0.05. b. BALF protein. Mean fold-effect ± SEM. 3-way ANOVA, Ozone x Recovery, p < 0.001. Tukey, *0 h vs 24 h within 0.8 ppm O3, #0 h vs 24 h within 0 ppm O3, p < 0.05. 2-way ANOVA, Ozone, p < 0.001. Tukey, †0 and 0.4 vs 0.8 ppm O3, p < 0.05. For detailed statistics, refer to Additional files 4 & 6. (Sample size, n = 8/air pollutant exposure group; n = 17/air control group)
