The Utility of Endoscopic Biopsies in Patients with Normal Upper Endoscopy

Table 4

Clinical predictors of abnormal biopsy on macroscopically normal EGDs on multivariable logistic regression.

Variable	Odds ratio	95% confidence interval	value
Esophageal biopsy
No NSAID	3.8	1.1–12.6	0.03
Gastric biopsy
Age <50 (years)	0.6	0.4–0.7	<0.0001
No anticoagulation	0.4	0.2–0.9	0.03
Duodenal biopsy
Age <50 (years)	1.6	1.0–2.6	0.04
Anemia	0.4	0.2–0.9	0.03
Dyspepsia	0.3	0.2–0.6	0.001

NSAID = nonsteroidal anti-inflammatory drug, EGD = upper endoscopy.
