Correlation between the items of the different recruitability indicators. A The correlation between the items of the different recruitability indicators showing a significant correlation between the recruitment-to-inflation ratio (R/I ratio) and the normalized maximal distance (rho = 0.74, P < 0.001). B The relationship between the maximal distance and the R/I ratio (rho = 0.31, P = 0.076,), and C between distance at 20 cm H2O and the R/I ratio (rho = 0.31, P = 0.082) were not correlated. D Moderate correlation was observed between normalized distance at 20 cm H2O and the R/I ratio (rho = 0.70, P < 0.001)
