I find this interesting, as at least one expert in my country was vocally unconvinced of the whole thing (he called it "baloney") when doctors reported thrombosis in 50 autopsies they had carried out and had suggested the use of heparin. Prior to this study there was a preprint by a Brazilian group but it was so poorly designed that it was impossible to gather any useful information. The actual paper is a bit light on details, and as the authors say, there are a lot of confounding factors, but it is a good step forward that requires further investigation.
