CKRT Circuit Life without Anticoagulation in Patients with COVID-19 and Controls. CKRT: Continuous Kidney Replacement Therapy. Kaplan-Meier survival curve of continuous kidney replacement therapy circuit comparing between COVID-19 patients and control in a subgroup which did not receive systemic or regional anticoagulation. In the absence of anticoagulation, there is significantly reduced survival of circuit amongst COVID-19 patients compared to control (p = 0.001)
