Continuous stellate ganglion block for neurovascular headache and associated anxiety and depression

Figure 2 Univariate analysis of prognostic factors affecting stellate ganglion block treatment efficacy. This figure presents univariate analysis results of potential prognostic factors associated with treatment efficacy. Treatment outcome at 3 months post-treatment (markedly effective and above vs effective and below) was used as the dependent variable. The red dashed line indicates the significance threshold at P = 0.05. Results show that age (P = 0.342), gender (P = 0.518), body mass index (P = 0.627), and headache type (P = 0.286) had no significant correlation with efficacy. However, disease duration (P = 0.008), baseline headache frequency (P = 0.012), medication overuse (P = 0.003), baseline Self-Rating Anxiety Scale score (P = 0.021), and baseline Self-Rating Depression Scale score (P = 0.015) were significantly correlated with efficacy. Variables with P < 0.10 were included in subsequent multivariate logistic regression analysis. Purple bars represent statistically significant factors (P < 0.05), while gray bars represent non-significant factors. BMI: Body mass index; SAS: Self-Rating Anxiety Scale; SDS: Self-Rating Depression Scale.
