Software and Algorithms Sentences Resources Statistical analysis was done in Python 3.7 using Kruskal-Wallis H-test and post-hoc Dunn’s test with Bonferroni correction. Pythonsuggested: (IPython, RRID:SCR_001658)Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).
Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:We are aware of certain limitations of our study, e.g. that it falls short of representative patient cohorts to compare mild with critical symptoms. Still, we were able to identify changes of blood cell physical phenotypes that did not return to the baseline healthy donor levels several months after SARS-CoV-2 infection, namely in erythrocytes and neutrophils. These alterations could be connected with long term symptoms of the recovered patients, of which 70% described chronic headache or neurological symptoms, 54% had concentration disorders and 62% circulatory problems like cold sweat and tachycardia. We hypothesize that the persisting changes of blood cell physical phenotypes could contribute to the impairment of circulation and oxygen delivery in coronavirus long haulers (17). Taken together, label-free physical phenotyping of blood cells with real-time deformability cytometry provides a fast, sensitive and unbiased way to feel for functional changes in cells. As such, deformability cytometry data has the potential to be used as a biomarker of COVID-19 and potentially other infectious diseases. In the future, RT-DC could be part of the first line of defense against an unknown virus during a pandemic.
