SNHG9 and hemoglobin measurement: Next, we performed the Kaplan-Meier survival analysis to determine the overall survival (OS) rate among 40 HB patients (20 high SNHG9 expression and 20 low SNHG9 expression patients) and found hepatoblastoma patients with high SNHG9 expression had a low 5-year survival rate (p=0.0161) compared to hepatoblastoma patients with low SNHG9 expression (Figure 2A).
