Figure 2 Changes in the visual analog scale score. A: Hypermenorrhea after microwave endometrial ablation. Values are expressed as the mean ± standard deviation (error bars). ^aP < 0.01 relative to the result before surgery; B: Dysmenorrhea after microwave endometrial ablation. Values are expressed as the mean ± standard deviation (error bars). ^aP < 0.01 relative to the result before surgery. MEA: Microwave endometrial ablation.
