TABLE 3.

Multivariable logistic regression examining labial salivary gland histopathology designation in past or current smokers compared with never smokers

Dependent variable (biopsy histopathology)	Independent variable (compared with never smoker)	Odds ratio	95% confidence interval	P value
Focal lymphocytic sialadenitis	Past smoker	0.59	0.38‐0.93	0.02
	Current smoker	0.25	0.14‐0.43	<0.001
Focal/sclerosing lymphocytic sialadenitis	Past smoker	0.70	0.42‐1.15	0.16
	Current smoker	0.26	0.13‐0.53	<0.001
Nonspecific chronic inflammation	Past smoker	0.66	0.41‐1.07	0.09
	Current smoker	0.53	0.29‐0.96	0.04
Sclerosing chronic sialadenitis	Past smoker	0.71	0.42‐1.19	0.19
	Current smoker	0.87	0.46‐1.67	0.68

Note: There were only four granulomatous inflammation histopathologic subtypes, so the odds ratio was not calculable.
