From: A combination of p300 and Braf expression in the diagnosis and prognosis of melanoma
Classification and Regression tree for differentiating primary melanoma from metastatic melanoma using Braf, nuclear p300 and cytoplasmic p300 expression. PM, primary melanoma, includes AJCC stages I and II cases. MM, metastatic melanoma, includes stages III and IV. ‘n’ indicates the number of samples and ‘%’ indicates the percentage of samples available at the respective node. Improvement is an indicator of separation achieved by the application of the respective marker to classify the parent node.
