Figure 2

Nausea visual analog scale scores of the two groups throughout the study period (line, the placebo group; dashed line, the TDS group). Arrows with numbers indicate the number of rescue antiemetics used (upper arrow, TDS group; down arrow, placebo group). The numbers indicate the total number of rescue antiemetics used at each time (“PACU”, use of rescue antiemetics in the PACU; “Arrival to GW”, immediately after arrival to general wards; “GW 4H”, the interval right before GW 4H). No arrow means “no use of rescue antiemetics”.
