Statistical Analysis:
All analyses were performed with the SPSS version 21. Descriptive data were given as percentages and as mean ± SD or median (IQR 25-75). The comparisons of ACT, VAS-symptom, TSS-6, VAS-QoL and MS between the pre-pandemic and during the pandemic periods were performed with the Wilcoxon signed rank test while the comparisons of ACT, VAS-symptom, TSS-6, VAS-QoL and MS between the groups were performed with the Kruskal Wallis H test. The scores of ACT, VAS-symptom, VAS-QoL, MS and TSS-6 during the pandemic were compared between the groups in pairs with the Mann Whitney U test. Categorical variables were evaluated using the chi-square test among groups and significant variables were further evaluated using the logistic regression analysis. Spearman correlation test was used to show the correlation between the delay in the application time of the patients and the differences in VAS-symptom, VAS-QoL, TSS-6 and MSs due to the pandemic. The power of correlation was defined as very weak if r<0.2, weak if r=0.2-0.4, moderate if r=0.4-0.6, strong if r=0.6-0.8, very strong if r>0.8. The results were assessed at a significant level of p<0.05 and a 95% confidence interval (CI).
