Giroux, MS, James Jett, MD, William D. Travis, MD, Masahiro Tsuboi, MD, Eric Vallières, MD, Peter Goldstraw, MB, FRCS  Journal of Thoracic Oncology  Volume 2, Issue 7, Pages (July 2007) DOI: /JTO.0b013e31807a2f81 Copyright © 2007 International Association for the Study of Lung Cancer Terms and Conditions

2 FIGURE 1 Running log-rank statistic for pathologically measured tumor size cutpoints, according to the T1 learning set (n = 2284; two thirds of patients with R0 pT1 tumors, by UICC6 classification). A running log-rank statistic is calculated and plotted on the y-axis for each possible cutpoint on the basis of pathologically measured tumor size (x-axis). The blue lines show log-rank statistics calculated on 100 random permutations of the data. The black line shows log-rank statistics for the actual data.
