Table 1.
Stratified mean values (and standard deviations) of patient and imaging characteristics for IAR (n = 33), IVR (n = 23) and NR (n = 34) patients.
| ADC Lesion Volume (mL) | Tissue-At-Risk Volume (mL) | Follow-up Lesion Volume (mL) | Age (years) | Percent Female | Initial NIHSS | Onset to Imaging (minutes) | |
|---|---|---|---|---|---|---|---|
| IAR | 19.65 (5.08) | 17.58 (5.32) | 50.85 (14.11) | 70 (1.76) | 52 | 15.85 (0.91) | 162.61 (17.71) |
| IVR | 7.50 (2.09) | 27.9 (6.11) | 32.22 (6.71) | 74 (2.74) | 78 | 14.30 (1.31) | 97.83 (12.28) |
| NR | 14.28 (3.33) | 21.71 (4.72) | 68.73 (12.1) | 75 (2.19) | 96 | 15.85 (0.89) | 171.76 (22.08) |
| significance | p = 0.131 | p = 0.430 | p = 0.138 | p = 0.086 | p = 0.255 | p = 0.524 | p = 0.026 |
p values were generated using the following tests: for sex frequency (Percent Female), Pearson’s Chi-squared; for initial NIHSS, Kruskal-Wallis H test; for ADC lesion volume, tissue-at-risk volume, follow-up lesion volume, age, and symptom-onset-to-imaging time, one-way ANOVA.
