Odds ratio and 95% CIs for salt-related factors and gastric cancer n (%)
| Salt factors | Cases | Controls | OR1 (95% CI) | P | OR2 (95% CI) | P value |
| Salted taste preference | ||||||
| Not salty | 118 (39.3) | 301 (50.2) | - | - | - | - |
| Medium | 162 (54) | 265 (44.2) | 1.12 (0.79-1.89) | P = 0.45 | 1.34 (0.92-2.67) | P = 0.08 |
| Salty | 20 (6.6) | 34 (5.7) | 1.33 (1.02-1.75) | < 0.05 | 1.94 (1.37-4.76) | < 0.05 |
| STST≥ 5 | 221 (73.7) | 258 (43) | 4.03 (2.87-5.65) | < 0.001 | 5.71 (3.18-6.72) | < 0.001 |
OR1 for salt related factors and gastric cancer was none-adjusted; OR2 was adjusted for age, sex, smoking, drinking, fresh fruit and fresh vegetables; STST: Salt taste sensitivity threshold. OR: Odds ratio.
