Leave-one-out cross validation where one of the total samples was removed, a prediction model was developed using the remaining samples, and the left-out sample was then predicted for sphere or adherent cells in each platform.

An output of 1 indicates that a left-out sample from adherent or sphere cells was predicted to be an adherent or sphere cell, respectively. An output of 0 indicates that a left-out sample from adherent or sphere cells was predicted as a sphere or adherent cell, respectively.
