Correlation (Spearman’s test) between the biomarkers and DNA analysis results

MNA10Ki67MAIp53DI FCMSPF FCMDI ICMSPF ICM
Note the strong correlation (R>0.65, bold) for the in situ biomarkers with each other, but not with the DNA cytometric features (either by ICM or FCM).
DI, DNA index; FCM, flow cytometry; ICM, image cytometry; MAI, mitotic activity index; MNA10, mean area of the 10 largest nuclei; P, probability of no significance (<0.05); R, correlation coefficient; SPF, S phase fraction.
