Correlation between severity of endoscopic findings and apnea-hypopnea index in patients with gastroesophageal reflux disease and obstructive sleep apnea

Table 4 Logistic regression analysis in terms of the severity of GERD1 and the relationship between BMI and AHI.

	Not-adjusted model	Adjusted at AHI2
BMI3	1.9 (0.64-5.88) 0.234	1.27 (0.38-4.15) 0.68
AHI3	4.09 (1.31-12.74) 0.016	3.79 (1.25-12.4) 0.028

¹Severity of GERD: mild: 0-1, severe: 2-4

²Classifying the AHI values: low: ≤the median of all patients (35); high: > the median of all patients (35);

³Classifying the BMI: low: ≤the median of all patients (33.8); high: >the median of all patients (33.8);

⁴Confidence interval; P<0.05 significant.
