Fig. 1From: Higher IGFBP-1 to IGF-1 serum ratio predicts unfavourable survival in patients with nasopharyngeal carcinomaCharacterization of plasma IGF-related cytokines levels in NPC patients and control individuals. Plasma levels of the following cytokines were analysed in NPC patient and control sera: a IGF-1; b IGF1-sR; c IGF-2 d IGFBP-1; e IGFBP-2; f IGFBP-3; g IGFBP-4; h IGFBP-6Back to article page
