Visual analogue scales(VAS) is extensively applied on evaluating symptomatic outcome data
such as the pain intensity
but currently most of the management of relevant data can’t conform to the statistical standard.This article categories the data measured with VAS and the eligible statistical methods
give a specific explanation about analysis of repeated measures data which may commonly misused in practice.It provides a reference criterion for statistical analysis with VAS in clinical research.
