Pooling—suppose we perform equal randomization in the current trial (n = 200 in each arm), but we pool the historical subjects with the current control subjects (thus, if we observe 140/200 = 0.70 in the control arm of the current study, with our 65/100 historical dataset, our actual control estimate would be (140 + 65)/(200 + 100) = 0.683).One could combine pooling with unequal This JAMA Guide to Statistics and Methods explains the use of historical controls—persons who had received a specific control treatment in a previous study—when [Skip to Navigation] Our website uses cookies to enhance your experience.
