MKI67 and neoplasm: Non-significant large numerical differences were observed in DDC1L according to Ki67 (Ki67 < 10%: median of 13.7 months versus ≥10%: 1.8 months; p = 0.1; Figure 1) and OS according to MIBG uptake (median of 72.6 for positive uptake versus 42.1 months for negative uptake; p = 0.13; Figure 2) by primary tumour location (supradiaphragmatic location: median of 221 × 71.3 months for adrenal and infradiaphragmatic; p = 0.28; Figure 3); or to tumour functionality (non-functioning tumours: median of 221 × 71.3 months; p = 0.39; Figure 4).
