Figure 8Randomized and nonrandomized comparative studies per center and cancer type

Each publication is represented by a red circle (randomized trials, RCTs) or a blue square (nonrandomized comparative studies, nonRCT) with size proportional to the logarithm of the total sample size.

The relative sizes of the markers are not in the same scale as in Figure 4 or in Figure 7.

The red and blue numbers in each cell denote the total number of RCTs and non randomized comparative studies, respectively.
