They may have enough in the control arm already ......there has probably been at least 15,000 ( ? ) Kaiser ASCVD prior event patients in the last 6 mths with no Covid . They just need to match those with 1600 ( ? ) of the same profile who have had Vascepa 4 gm daily added.
Both groups need to stay the same for a minimum of 6 mths
So in the control arm ..... even If you start the recruiting period from the last Covid peak in Nth Ca .....you are probably only asking those patients to not start Vascepa for another 3 mths .
Remember ...this is using electronic records
As we know ...R-IT could have been stopped at Interim 2 ...but DMC decided to continue . Was that ethical ?
