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

Table 3 Cox multivariate analysis demonstrating the risk of acute rejection in patients with post-lung transplant hypocontractility, compared to post-transplant normal motility, controlling for confounders

Covariate	Cox multivariate analysis hazard ratios for ACR	P value
Post-transplant hypocontractility vs post-transplant normal motility	2.63 (1.11-11.8)	0.03
Post-transplant hypercontractility vs post-transplant normal motility	2.81 (0.80-9.85)	0.10
Borderline (AET 4%-6%) vs normal (AET < 4%) pre-transplant acid reflux	0.43 (0.05-3.35)	0.42
Abnormal (AET > 6%) vs normal (AET < 4%) pre-transplant acid reflux	1.65 (0.20-13.8)	0.64
Lungs transplanted	2.45 (0.30-20.2)	0.40
Age at transplant	0.99 (0.92-1.06)	0.77

ACR: Acute cellular rejection; AET: Acid exposure time.
