For CRC there was a linear relationship between the predicted and the real data with a correlation of 0.99 (p < 0.001), except for CD4 cells (Figure 4A), for which actual proportions between 25% and 75% were slightly underestimated, with yet a good overall correlation of 0.94 (p < 0.001). Here, CD4 is linked to colorectal carcinoma.
