Until December 2020, 1011 KT with COVID-19 have been prospectively included in the Spanish Registry and followed until recovery or death. In multivariable analysis, age, pneumonia, and KT performed ≤6 months before COVID-19 were predictors of death, whereas gastrointestinal symptoms were protective. Survival analysis showed significant increasing mortality risk in four subgroups according to recipient age and time after KT (age 6 months, age 6 and age ≥65 and time ≤6): mortality rates were, respectively, 11.3%, 24.5%, 35.4%, and 54.5% (p  YR 2021 FD 2021-04-12 LK http://hdl.handle.net/10668/17389 UL http://hdl.handle.net/10668/17389 LA en DS RISalud RD Apr 14, 2025
