EHD1 and osteosarcoma: Univariate Cox regression model analysis showed that age (P = 0.015; HR, 0.945; 95% CI, 0.903–0.989), tumor size (P = 0.042; HR, 3.155; 95% CI, 1.045–9.525), and EHD1 expression (P = 0.026; HR, 3.202; 95% CI, 1.149–8.92) were independent prognostic indicators of OS in osteosarcoma patients (Table 3).
