Respiratory Measures Over Time for Angiotensin-II versus Placebo. Displays respiratory variables over time by treatment group. Black indicates the placebo group, pink the Ang-II group. Error bars display the SEM. Asterisks display the p-value for the between-treatment group difference at the indicated timepoint, adjusted for the baseline value, from the regression model as follows: *p < 0.05; **p < 0.01; ***p < 0.001. Hashmarks show the within-treatment difference versus the baseline as follows: ^#p < 0.05; ^##p < 0.01; ^###p < 0.001. Ang-II angiotensin-II, PEEP positive end-expiratory pressure, mAwP mean airway pressure, SEM standard error of the mean
