Effects of Chinese acupuncture on nausea and vomiting after cholecystectomy: A retrospective study

Figure 2 Comparative analysis of acupuncture effects on post-operative nausea and vomiting. A and B: This figure demonstrates that acupuncture significantly reduces post-operative nausea and vomiting incidence rates across overall, laparoscopic, and open surgery groups compared to control groups (A), while also achieving substantially lower visual analogue scale severity scores (B). All comparisons show statistical significance, indicating acupuncture’s consistent therapeutic efficacy in preventing and alleviating post-operative nausea and vomiting regardless of surgical approach. ^aP < 0.05.
