IGFBP3 and meningioma: In fact, endothelial VEGF, IGFBP-3, and PlGF expression was found in 52% (n = 151), 61% (n = 177), and 47% (n = 136) of meningiomas, which differed significantly between meningiomas with FTV (58% (n = 87); 62% (n = 109); 62% (n = 84)); and without FTV (42% (n = 64); and 38% (n = 68) and 38% (n = 52); p < 0.001, respectively; Figure 3F–H).
