Comparison between the Visual Analog Scale and the Numerical Rating Scale in the perception of esthetics and pain

There was a concordance between the scales with regard to esthetical perception and the evaluation of pain. When assessing esthetics, the order in which the two scales are applied does not affect the concordance between them. However, the strength of the concordance is influenced. Esthetic perception is not influenced by the differences between the panels of evaluators. The concordance between the two scales, for the evaluation of pain, increases proportionally with the level of formal education.
