Legend: Comparison of variables regarding pain location and measurements according to two different one-dimensional scales; NRS stands for numerical rating scale, and VAS stands for visual analogue scale. Continuous variables are described as the mean ± SD or median [25th – 75th percentile]; Student’s t-test and Mann-Whitney’s test, respectively, were used, according to variables’ distribution. Categorical variables are expressed as the absolute and relative frequencies, n (n%), respectively.
