Effect of seasons (hot or cold) on stroke outcomes.
| Outcome |
All stroke N (%) (n = 1,271) |
Hot N (%) (n = 774) |
Cold N (%) (n = 497) |
P |
|---|---|---|---|---|
| Median NIHSS score on discharge (0–42) (IQR) | 3.0 (1.0–8.0) | 3.0 (1.0–9.0) | 4.0 (1.0–8.0) | 0.816 |
| Dependent on discharge* | 378 (29.7) | 230 (29.7) | 148 (29.8) | 0.981 |
| ICU admission | 140 (11.0) | 84 (10.9) | 56 (11.3) | 0.795 |
| Median LOS (days) | 6.0 (3.0–15.0) | 6.0 (3.0–15.0) | 7.0 (4.0–15.0) | 0.528 |
| Medical complications | ||||
| - Pneumonia | 73 (5.7) | 37 (4.8) | 36 (7.2) | 0.066 |
| - Urinary tract infection | 95 (7.5) | 57 (7.4) | 38 (7.6) | 0.852 |
| - Deep vein thrombosis/pulmonary embolism | 20 (1.6) | 16 (2.1) | 4 (0.8) | 0.078 |

A p-value of < 0.05 was considered statistically significant.
NIHSS, National Institutes of Health Stroke Scale; ICU, intensive care unit; LOS, length of stay; mRS, modified Rankin scale.
*
Check only those with mRS (3–5) on discharge and compare among seasons.
