Fig. 4

Comparative Kaplan-Meier curves of each premedicated tablet or capsule transiting beyond the stomach. Lead time is the time from premedication administration to specimen resection. A shadowed area indicates the 95% confidence interval of the predicted probability. The dashed line indicates the median complete transit time (135 min [95% CI: 120 min ‒ 165 min] for tapentadol, 119 min [95% CI: 100 min ‒ 133 min] for netupitant/palonosetron). Each step-up indicates the case of patients where the premedication was not observed in the specimen; each cross indicates a case where the premedication was observed in the specimen
