RECIST was applied to tumor volumes to compare to the unidimensional linear methods. A total of 9 tumors at 14 time points were available for rechecks. PR = partial response (solid gray), PD = progressive disease (solid black, white lettering), and SD = stable disease (solid white). One dog was not included in this table because it was only measured at one time point.
