From: Cigarette smoke worsens lung inflammation and impairs resolution of influenza infection in mice
Change in body weight of mice during the experimental period. Influenza (â– ; n = 12), smoke alone (â–²; n = 8) and smoke and influenza (- â—† -, n = 12). Mice lost weight while smoke exposure was underway, and once exposure stopped, weight was regained but this was impaired in smoke and influenza mice. Mice were first weighed 3 days before smoke exposure began and weights are expressed as mean change from this starting weight, +/- SEM. Data were analyzed by one way ANOVA with repeated measures followed by a post hoc Fisher's protected least significant difference test. The * symbol indicates a statistically significant difference in mean weight between smoke alone and smoke and influenza mice, at that time point. The # symbol indicates a statistically significant difference in mean weight between influenza alone and smoke and influenza mice at that time point.
