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

Figure 1 Self-Rating Anxiety Scale score changes over time following stellate ganglion block treatment. The graph illustrates the dynamic changes in Self-Rating Anxiety Scale (SAS) scores from baseline through 3 months post-treatment (n = 126). The blue line represents mean SAS scores with standard deviations at each time point, while green bars indicate the percentage reduction from baseline. SAS scores significantly decreased from baseline 52.4 ± 8.3 to 1 week 48.6 ± 8.1 (7.3% reduction, t = 4.87, P < 0.001), with further improvement at 1 month 43.6 ± 7.8 (16.8% reduction, t = 11.24, P < 0.001). The optimal therapeutic effect was achieved at 1-month post-treatment and maintained stably through 3 months (44.2 ± 8.0, 15.6% reduction, t = 10.68, P < 0.001), with no significant difference between 1 month and 3 months (t = 0.64, P = 0.523). Data presented as mean ± SD. Statistical significance determined by paired t-tests. SAS: Self-Rating Anxiety Scale.
