Comparison of clinical outcomes between the DEX and LA groups after PSM. A: Difference in the improvement of GAD-7 scores from baseline [−4.43 (95% CI, −4.98 to −3.88) vs. −2.42 (95% CI, −2.97 to −1.87); P < 0.001]. B: Difference in the improvement of PHQ-9 scores from baseline [(−6.19 (95% CI, −6.84 to −5.55) vs. −3.92 (95% CI, −4.56 to −3.28); P < 0.001]. C: Difference in the improvement of NRS scores from baseline [−3.32 (95% CI, −3.58, −3.05) vs. −2.62 (95% CI, −2.88, −2.36)]. PSM, Propensity score matching. DEX, Dexmedetomidine. LA, Local anesthesia. GAD-7, 7-item Generalized Anxiety Disorder questionnaire, PHQ-9, 9-item Patient Health Questionnaire. NRS, numerical rating scale. CI, confidence interval
