Ref.	Country	Patients	Patients with LT	Main findings

Belli et al[47]	International	103	103 (100)	Mortality might correlate with age and longer time since LT
Donato et al[49]	Italy	640 (8 COVID positive)	640 (100)	Low prevalence of infection in LT patients who adhere to preventive measures
Lee et al[48]	United States	38	38 (100)	High mortality in LT patients regardless of time since transplant
Pereira et al[46]	United States	90	14 (15)	Solid organ transplant recipient had more severe outcomes
