Comment on "Evaluation of Complication Rates after Breast Surgery Using Acellular Dermal Matrix: Median Follow-Up of Three Years".

I read with great interest the article by Paprottka et al. [1] which presented the results of a study on complications after breast surgery. The publication of such a study is important for both surgeons and patients, in order to make an informed decision on the expected outcomes of such an invasive surgery. In particular, patients should be aware of the risks involved in such an intervention.Therefore it is of the utmost importance that the design of such a study is correct and that the conclusions are justified by the data. I am concerned with both of these aspects of the study, as well as fundamental dissimilarities in the devices as well as the patient cohorts.
