Multivariate models predicting reflux exposure
| Reflux parameter | aOR (95% CI)a | P value |
| AET | 0.89 (0.74–1.05) | 0.19 |
| BET | 0.88 (0.74–1.02) | <0.10 |
| Pharyngeal events | 0.83 (0.69–0.98) | 0.04 |
| Total reflux episodes | 0.65 (0.39–0.96) | 0.06 |
All models were controlled for age, sex, BMI, smoking status, and percentage of ineffective swallows.
AET, acid exposure time; aOR, adjusted odds ratio; BET, bolus exposure time; BMI, body mass index; CI, confidence interval; PCI, proximal contractile integral.
ORs are expressed per 100 mm Hg-s-cm change in PCI.
