Concerns have been raised regarding the integrity of Figures 3, 4, and 5. These functions appear to be drawn with inconsistent line quality and contain unexpected background artifacts, which is not explained by the content of the article.
In response to these concerns we contacted the authors to clarify the situation and request the original data so that we may assess the nature of these claims. The authors have not responded to our queries within the requested timeframe. Therefore, as the original data is not available for review, we cannot confirm the integrity of data presented within the article.
The Editors and Publisher of Drug Development and Industrial Pharmacy would like to alert readers of this. We will provide an update if we receive any further information.
