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

Table 2 Cox multivariate analysis demonstrating the risk of acute rejection in patients with change in failed swallows as a continuous variable from pre- to post-lung transplant, controlling for confounders

Covariate	Cox multivariate analysis hazard ratios for ACR	P value
Change in failed swallows, per 10% increase	1.20 (1.01-1.43)	0.03
Borderline (AET 4%-6%) vs Normal (AET < 4%) pre-transplant acid reflux	0.32 (0.04-2.49)	0.27
Abnormal (AET > 6%) vs Normal (AET < 4%) pre-transplant acid reflux	1.33 (0.17-10.4)	0.79
Lungs transplanted	1.64 (0.20-13.6)	0.65
Age at transplant	0.99 (0.92-1.06)	0.70

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