Table 1 Demographic characteristics and NQO1 polymorphism among ESCC, GCA patients and controls

Groups	Control n (%)	ESCC n (%)	GCA n (%)
Sex
Male	109 (66.1)	124 (64.3)	92 (74.2)
Female	56 (33.9)	69 (35.7)	32 (25.8)
Mean age ± SD (yrs)	52 ± 7.16	59 ± 8.73	60 ± 8.24
Smoking status
Smoker	82 (49.7)	104 (53.9)	68 (59.8)
Non-smoker	83 (50.3)	89 (46.1)	46 (40.2)
Family history of UGIC
Positive	0	86 (44.6)	45 (36.3)
Negative	165 (100)	107 (55.4)	79 (63.7)
Genotype
C/C	52 (31.5)	51 (26.4)	40 (32.3)
C/T	86 (52.1)	92 (47.7)	55 (44.3)
T/T	27 (16.4)	50 (25.9)^a	29 (23.4)
Allele type
C	190 (57.6)	194 (50.3)	135 (54.4)
T	140 (42.4)	192 (49.7)^b	113 (45.6)

Note. ESCC: esophageal squamous cell carcinoma; GCA: gastric cardiac adenocarcinoma; NQO1: NAD(P)H: quinone oxidoreductase 1; UGIC: upper gastrointestinal cancer; a. The genotype frequency was significantly higher than that in healthy controls (χ² = 4.79, P = 0.028); b. The allele frequency was marginaly higher than that in healthy controls (χ² = 3.83, P = 0.05).
