A Genomic Strategy to Refine Prognosis in Early-Stage Non–Small-Cell Lung Cancer . Figure 4 presents an analysis of samples from a Cancer and Leukemia Group B (CALGB) 9761 trial conducted to validate the performance of a predictive model for early-stage non–small-cell lung cancer (NSCLC). Some of the samples used for this analysis were from a study that was a lead-in to CALGB 9761, collected under a protocol that formed the basis for CALGB 9761 but before the official initiation of the trial. Review of these data also identified a systematic error in the entry of patients' ages in the database, along with a few additional errors in data on clinical stage and survival that do not affect the results or conclusions presented. Supplementary Tables 1 and 3, available on the Journal's Web site (www.nejm.org), now contain the corrected data. Also, the microarray data for the CALGB samples were generated as part of the National Cancer Institute (NCI) Director's Challenge Lung Cancer Study and are now available at the NCI Lung Cancer Web site (http://caarraydb.nci.nih.gov/caarray/; select "Search experiments" and enter the name of that study). Finally, the legends to Figures 3, 4, and 5 should have read "Tick marks indicate patients whose data were censored by the time of last follow-up or owing to death," rather than "by the time of last follow-up owing to death." The article has been corrected on the Journal's Web site.
