Table 2. Characteristics of the subjects categorized according to the smoking status.
| Characteristic | Smoking status | |||
|---|---|---|---|---|
| No smoker (n=1,297) (1,292 for fibrinogen) |
Past smoker (n=1,188) (1,186 for fibrinogen) |
Current smoker <20/day (n=1,362) (1,356 for fibrinogen) |
Current smoker ≥20/day (n=1,130) (1,125 for fibrinogen) |
|
| Uric acid, mg/dL | 6.0±0.033 | 6.1±0.035 | 5.9±0.032 | 5.8±0.035 |
| C-reactive protein, mg/L | 0.33 (1.03) | 0.35 (1.03) | 0.34 (1.03) | 0.39 (1.03) |
| Fibrinogen, mg/dL | 240.5±1.17 | 240.6±1.23 | 246.9±1.14 | 253.2±1.25 |
Values for uric acid and fibrinogen are presented as arithmetic mean±standard error or for C-reactive protein are presented as geometric mean (standard error). Age was adjusted at 42.7. Jonckheere-Terpstra trend test showed all significance with P<0.001.
