Comparison of the mean relative antioxidant defense enzyme mRNA expression in the patients with the best prognosis to those with the worst prognosis. Bars represent the mean relative mRNA expression, on a log2 scale, for the 10% of the patients with the best (□) and worst (▪) prognosis from the LLMPP microarray, plus or minus the standard error of the mean (SEM). Gene names are abbreviated as in Table 1.
