Correlation (Spearman’s test) between the biomarkers and DNA analysis results
| MNA10 | Ki67 | MAI | p53 | DI FCM | SPF FCM | DI ICM | SPF 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. | |||||||||
