Associations of physical activity with ICH volume
| Physical activity <4 hour/week | Physical activity ≥4 hour/week | β (SE) | P value | |
| Deep ICH, median volume (IQR) | 11.7 (4.3–28.3) | 5.9 (1.8–13.1) | −0.35 (0.08)* | <0.001 |
| −0.36 (0.09)† | <0.001 | |||
| Lobar ICH, median volume (IQR) | 30.3 (7.6–71.7) | 15.1 (4.8–39.0) | −0.24 (0.10)* | 0.018 |
| −0.23 (00)† | 0.016 | |||
| Infratentorial ICH, median volume (IQR) | 8.0 (2.1–17.9) | 3.9 (0.8–10.5) | −0.35 (0.14)* | 0.017 |
| −0.29 (0.18)† | 0.114 |
Associations of prestroke physical activity with haematoma volume in deep, lobar and infratentorial ICH were calculated in multivariate linear regression models. Results were obtained from imputed data.
*Adjusted for age, sex, education, time to scan and International Normalised Ratio (INR).
