“ Significance: Among patients with COVID-19, the use of HCQ could significantly shorten TTCR and promote the absorption of pneumonia.”
From Paper:
TTCR: Time to clinical recovery
edit: got downvoted, so adding link to only other "absorption of pneumonia" use that I could find: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5344839/
edit2: I could also find some usage of "absorption of inflammation", again also all Chinese researchers.
I will assume that 'absorption' in this sense refers to the fluid. It's a good thing when this happens, because that that area of the lung can be accessed by air again.
