Increase in failed swallows from pre- to post-lung transplant esophageal function testing is associated with acute rejection

Table 4 Correlation with change in failed swallows

	Spearman’s correlation	P value
Baseline FVC, %-predicted	R = -0.19	0.16
Baseline FEV1, %-predicted	R = -0.16	0.23
Baseline FEV1/FVC	R = -0.02	0.87
Baseline TLC, %-predicted	R = -0.32	0.05
Change in bolus clearance	R = -0.45	0.004
Change in ineffective swallows	R = +0.51	< 0.0001

FVC: Forced vital capacity; FEV1: Forced expiratory volume; TLC: Total lung capacity.
