  1. P-values were calculated using independent-sample t-test in the case of normal distribution and Mann-Whitney U in case of non-normal distribution. For categorical data, the chi-square test with Yates’s correction was used. n number of patients, SD standard deviation, V volume, TG thyroid gland, TN thyroid nodules, (Q1 – Q3) quartile range
