| Mean platelet volume, fl | 9.9±0.8 | 10.2±1.08 | 0.043* |
| PVI | 5.3±1.9 | 6.7±2.3 | 0.000* |
| C‐reactive protein (0-6 mg/L) | 26.8±4.2 | 57.7±6.8 | 0.010* |

SD = standard deviation; WBC = white blood count; PVI = platelet volume index; Mann-Whitney U test was used on statistical analysis; *p<0.05 was considered significant
