Values are expressed as means ± SD; EI: elongation index and Pa: pascal. : difference between the control group, before treatment of newly diagnosed COPD, and the exacerbation group; : difference between the control group, after treatment of newly diagnosed COPD, and the exacerbation group; < 0.05: difference from control, < 0.05: difference from before treatment of COPD, and < 0.05: difference from after treatment of COPD. and are findings via ANOVA whereas other symbols are findings by comparison of two groups.
