  • Values are expressed as median (minimum–maximum). The variables were compared with Mann-Whitney U-test and Chi-square (χ2) test. A p<0.05 probability value was considered statistically significant.

  • *Mann-Whitney U-test, p<0.05.

  • †Chi-square (χ2) test, p<0.05.

  • VAS, Visual Analogue Scale.
