Context:
We randomly assigned eligible patients who had received intravenous t-PA within 3 hours after symptom onset to receive additional endovascular therapy or intravenous t-PA alone, in a 2:1 ratio. The primary outcome measure was a modified Rankin scale score of 2 or less (indicating functional independence) at 90 days (scores range from 0 to 6, with higher scores indicating greater disability).
@oristarA,
No. Normally, it is read as 'two to one'.
Roger's right. It means twice as many patients got the additional therapy plus the intravenous t-PA as just got the intravenous t-PA.
