Fig. 6From: Where is the limit of prostate cancer biomarker research? Systematic investigation of potential prognostic and diagnostic biomarkersKaplan-Meier curves for nine top-ranked genes with substantial expression in prostate cancer, statistically significant and independently associated with biochemical recurrence-free survival of the patients with prostate cancer in multivariate Cox regression analysis (median of expression as dichotomization cut-off). Abbreviations: Median – median of mRNA expression, HR – hazard ratio, l95% CI and u95% CI – lower and upper 95% percentile of the confidence interval (CI), low expression – expression levels below cut-off, high expression – expression levels above cut-offBack to article page
