With stratification of the cohort based on BMI (≤29.9 kg/m2) and HOMA-IR, FGFR1 was decreased in PCOS (p < 0.001), and VEGF-D (p < 0.04), IGF1 (p < 0.04), and IGF-1sR (p < 0.02) were decreased in PCOS compared to controls, as shown in Table 4 and Figure 4. Here, IGF1 is linked to polycystic ovary syndrome.
