Wet-to-dry ratio. a All wet-to-dry ratios from lung tissue samples in the experiment, bars indicate the mean value in each group, sample number in Protective and Control were 48 each and in the sham groups 12 each. b Wet-to-dry ratios at the three sample levels (cranial, middle, caudal) used in the general linear model analysis of the two main groups Protective and Control, spreads are mean ± SE, the statistical test refers to group difference and not differences at individual levels, * denotes p < 0.01
