Fig. 4

Boxplots showing comparison of measured first expiratory time constant (τ1) with each of the other five methods of τ calculation in: A pressure-controlled ventilation (PCV) and B volume-controlled ventilation (VCV). Values are displayed as means, IQRs and 95% confidence intervals (black cursors within the boxplots). Mean of the measured τ1 is represented as the dashed red line. The five methods of τ determination were compared with the measured τ1 as the reference using the Dunnett’s post hoc test, displaying adjusted p values
