Dear Ms. Goddard,
I have been working in a review article and I would like to classify the studies according to the Oxford Evidence Level, but I have a doubt. Two studies are crossover types with random assignment; one has statistical power of 0.074 and the other has no statistical power calculation. Could I consider them as randomized control trial (RCT) level 2b?
Thank you very much for your attention.
Cordially,
Geana Paula Kurita
