All enrolled patients had blood collected into a citrated tube for coagulation assessment using thromboelastography with the TEG®6s, Haemonetics, Braintree, MA, USA, at three set time points during hospital admission:

Time point 1 (day of admission, either before enoxaparin administration or at least four hours after enoxaparin administration)

Time point 2 (48 hours, three hours postenoxaparin administration)

Time point 3 (resolution of hypoxemia—off oxygen therapy, three hours postenoxaparin administration) or on day 10 of admission, whichever occurred first

Patient demographic, clinical, laboratory, and hospital survival data were extracted from clinical notes. The following scores were calculated from the clinical information: disseminated intravascular coagulation (DIC) score as per International Society on Thrombosis and Haemostasis (ISTH) criteria [18 (link)], sepsis-induced coagulopathy (SIC) score [19 (link)], simplified acute physiology score 2 (SAPS2) [20 (link)], and sequential organ failure assessment (SOFA) scores [21 (link)], at the above three time points unless the enrolled subject was discharged or demised before the defined time.
