Prognostic value of IGF-1 and IGF-1R in subtypes of PCa patients defined by T2E. First quartile values of RQ were separately calculated for the T2E–negative (top) and T2E-positive (bottom) groups, and the samples were classified as high-expressers (H) and low-expressers (L). Time scale refers to months from diagnosis. Black lines indicate high-expression patients. BPFS, biochemical progression-free survival; PFS, clinical progression-free survival. The number of patients at risk in the high- (top) and low-expression (bottom) samples is listed above each time interval
