Table 1a.
Characteristics of the 278 Patients from Institution 1, stratified by “poor” (mRS 0–3) and “good” (mRS 4–6) outcomes. Percentages are rounded to the nearest whole number. Footnotes are provided by variable names to indicate significant differences in medians between groups at an α level of .05 using Mood’s median test using the “RVAideMemoire” package in R33.
| “Poor” outcome N = 204 |
“Good” Outcome N = 74 |
