The strength of association of follow-up infarct volume with functional outcome of the total population, and per imaging modality and follow-up acquisition time
| FIV assessment | Spearman ρ | 95% CI | P value |
| Full population | 0.58 | (0.55 to 0.62) | <0.0001 |
| CT | 0.57 | (0.53 to 0.61) | <0.0001 |
| MRI | 0.59 | (0.51 to 0.66) | <0.0001 |
| ≤48 Hours | 0.60 | (0.56 to 0.64) | <0.0001 |
| >48 Hours | 0.55 | (0.50 to 0.60) | <0.0001 |
