A: Experiments performed at DFR 20 L/min. B: Experiments performed at DFR 25 L/min. C: Experiments performed at DFR 30 L/min. Data are presented as mean ± SEM (n = 3). Statistically significant results are marked with asterisks (*). A single asterisk indicates p ≤ .05. Two asterisks indicate p ≤ .01. Three asterisks indicate p ≤ .001Back to article page
