The effect of metabolic syndrome components on oral potentially malignant disorders

	All OPMD
	aRR*	95% CI	P value
Component of metabolic syndrome
Central obesity	1.22	1.04 to 1.44	0.0162
Hypertriglyceridaemia	1.26	1.07 to 1.49	0.0066
Low HDL-C	1.12	0.95 to 1.32	0.1851
Elevated blood pressure	0.93	0.79 to 1.09	0.3586
Hyperglycaemia	1.20	1.02 to 1.41	0.0297
Metabolic syndrome score	1.14	1.08 to 1.20	<0.0001

*aRR for components of metabolic syndrome and metabolic syndrome score were treated in different models with adjustment of age, sex, education level, betel nut chewing, cigarette smoking, alcohol drinking, meat, vegetable and fruit consumption.

aRR, adjusted rate ratio; HDL-C, high-density lipoprotein cholesterol; OPMD, oral potentially malignant disorder.
