Fig. 6. Scatter plot of DOSS and PVST parameters. At each time point, a scatter plot is depicted, and Spearman's correlation test was performed. (A) Preoperatively (n=21), the correlation coefficient (R) value was 0.702 (p<0.001). Postoperatively, R values were 0.539 (p=0.012) after 1 month (n=21) (B) and 0.566 (p=0.020) at last follow up (n=17) (C). DOSS, Dysphagia Outcome and Severity Scale; PVST, prevertebral soft tissue thickness.
