Table 2.

Adjusted odds ratios (ORs) and corresponding 95% confidence intervals for the risk of Barrett's esophagus in relation to cigarette smoking status and smoking cessation (cases vs. population controls)

	# BE/Pop controls	Cases vs. Population controls OR (95%CI)
Smoking status^*

Non-smoker	108/140	1 (ref)
Ever smoker	212/176	1.32 (0.94-1.85)

Current smoker	51/39	1.09 (0.68-1.74)
All former smokers	161/137	1.35 (0.94-1.94)

# Years since smoking cessation^**

Less than 5years	19/8	3.69 (0.90-15.1)
5-14.9	36/25	2.84 (0.99-8.11)
15-24.9	38/33	1.37 (0.59-3.18)
25+	38/71	1.14 (0.66-1.97)
Per year since quit smoking		0.98 (0.95-1.00)
p-value for trend		0.07

The model was controlled for age, race (white vs. non-white), gender, and education

^**

The model was controlled for all the above mentioned variables plus pack-year of smoking.
