Degree centrality (denoted dc)): This is given by the proportion of nodes directly connected to the target node.
Another subset is the proportion of nodes involved.
Considering the proportion of nodes and connections (11 nodes / 19 connections) the network appears to be sparsely connected.
The distribution P(k) gives the proportion of nodes in the network having degree k.
We investigate an idea that has surfaced recently in the literature (since 1999), namely that the proportion of node-positive lymph nodes (or a function thereof) is a much better predictor of survival than the number of excised and node-positive lymph nodes, alone or together.
In both groups, the proportion of node-positive cases was positively associated with tumour size (P=0.000).
In this report the modeling utility of the proportion of involved nodes is compared with the absolute numbers of involved nodes and of examined nodes.
Accuracy of clinical evaluation varied significantly according to the type of cancer, node positivity, and the proportion of positive nodes with respect to the total number of nodes.
We also evaluated whether the radiotracer injected affected the proportion of positive nodes removed in node-positive patients.
However, the proportion of anchor nodes in all sensor nodes is relatively small.
