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).
