Comparison of coagulation dysfunction among patients stratified by heatstroke and heatstroke-induced coagulopathy.
| Characteristics | Non-heatstroke group (n = 171) | Heatstroke groups |

| HIC score | 0 (0, 0) | 1 (0, 1)a | 4 (3, 5) ab | 141.667 | < 0.001 |
| In-hospital mortality (%) | 0 (0) | 0（0） | 7 (19.4) | 31.072 | < 0.001 |
Values are median (Q1, Q3), unless otherwise indicated.
ap < 0.05 compared with the non-heatstroke group.
bp < 0.05 compared with the non-HIC group.
PT: prothrombin time; INR: international normalized ratio; APTT: activated partial thromboplastin time; HIC: heatstroke-induced coagulopathy.
