Table 4

Assessment of numerical rating scale (NRS).

Time points	Groups		value
	PECS II	Placebo
1 (PACU), , h
Cough			<0.05
Rest			<0.05
4, , h
Cough			<0.05
Rest			<0.05
24, , h
Cough			>0.05
Rest			>0.05

All the data values are presented as mean (standard deviations). 1 h (PACU): evaluation of NRS at PACU is regarded as the time point of 1 h after operation. Cough: dynamic NRS at 1, 4, and 24 h after operation are induced by coughing.
