aCR rates for up to 120 h of TACE derived using the Kaplan–Meier method. The aCR rates for up to 24 h were 90.3% and 89.2% for the olanzapine and control groups, respectively. After 24 h, there was a gradual difference between the two groups, with the aCR rate of 90.3% for olanzapine and 70.3% for the control group at 120 h after TACE. The Mantel-Haenszel HR for the olanzapine group compared to the control group was 0.26 (95% CI 0.09–0.77, p < 0.05), indicating a significantly lower hazard of nausea and vomiting in the olanzapine group.　aCR; antiemetic complete response, TACE; transcatheter arterial chemoembolization, HR: hazard ratio, CI; confidence interval.
