Change in Author Names

In the original version of our article [1], insufficient acknowledgement was given for the proteomic experiments, sample selection, analysis of results and drafting of the manuscript. We apologize for the original error and any inconvenience caused by the omission of Sarah Strohkamp as an author. To correct this oversight, Sarah Strohkamp has been added as an author including a shared first authorship.

The corrected author list is provided below:

Timo Gemoll ^1,*^,†, Sarah Strohkamp ^1,†, Svitlana Rozanova ¹, Christian Röder ², Sonja Hartwig ^3,4, Holger Kalthoff ², Stefan Lehr ^3,4, Abdou ElSharawy ^5,6 and Jens K. Habermann ^1,7

Change in Main Body Paragraphs

We have found two inadvertent errors in our paper published in the Journal of Clinical Medicine [1].

(1)

In the original article, there was a mistake in the legend for Figure 2. Labeling of proteins more greatly expressed in respective groups was inverted. The correct legend appears below. The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected.

Figure 2. Supervised PCA plots based on 226 (A) and 93 (B) significant spots obtained by ultra-centrifugation or ExoQuick™. Red, proteins with higher expression isolated by ExoQuick™; green, proteins with higher expression isolated via ultracentrifugation.

(2)

In the original article, there was a mistake in Supplementary Table S1. The table presents the mean and not the median of the patient cohort. The corrected Supplementary Table S1 was changed accordingly and was included as a separate document. The authors apologize for any inconvenience caused and state that the scientific conclusions are unaffected.

3. 

Change in Figures/Tables

The author wishes to make the following correction to this paper [1]. Due to mislabeling in Figure 2, this figure has to be replaced with the corrected version:

Old Figure 2 with mislabeling:

New corrected Figure 2 for replacement:

Change in Acknowledgement

Due to a change in the author list, the Acknowledgement section was deleted from the original article version [1].
