Bidirectional association between serum carcinoembryonic antigen and metabolic syndrome among the Chinese male population: two cohort studies

Table 6 The hazard ratio (95% CI) of smoking among different CEA status in subcohort A

Characteristics	No. of patients with MetS	Event rate %	β	Hazard ratio for MetS^a	P
Hyper-CEA (n = 547)
Smoking	47	16.49	−0.064	0.94 (0.55, 1.59)	0.814
Nonsmoking	41	15.65		1
Norm-CEA (n = 5861)
Smoking	533	24.42	0.022	1.02 (0.9, 1.16)	0.742
Nonsmoking	742	20.17		1

^a: The hazard ratio was adjusted for age, alcohol intake, the components of MetS, blood uric acid, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, haemoglobin and white blood cell count. CEA Carcinoembryonic antigen; Hyper-CEA Elevated serum CEA level above the reference range; Norm-CEA Within the normal reference ranges; MetS Metabolic syndrome
