Letter to the Editor of the Journal of Artificial Organs: The flaws in the detail of describing methods, comparing patient cohorts and interpreting results.

We read with great interest the article written by Murphy et al. (J Artif Organs 22:286-293, 2019). We acknowledge the authors contribution. However, the results presented may be difficult to interpret due to several missing information and therefore may not support the conclusions. Therefore, the results of this publication should be viewed very critically.
