Abstract

Use of the six-minute walk test has been proposed as a prognostic marker in liver cirrhosis. In the Letter to the Editor presented here, the authors highlight some important points, which were raised after the article was published in the November issue of the World Journal of Hepatology.

Keywords: Six-minute walking test; Liver cirrhosis; Hospital admission and mortality

Core Tip: We advocate the use of the six-minute walk test, a practical and simple way to assess risk and provide a better understanding of how exercise limitation can directly affect the survival of cirrhotic patients; however, we emphasize the importance of interpreting it by using appropriate reference equations for a given population.
