Seventeen studies [7, 8, 16, 21, 24–30, 35, 38–41, 45] included both adult and paediatric transplant recipients, 13 studies [4–6, 15, 18–20, 22, 23, 34, 36, 42, 43] only included adult patients ≥18 years old and five studies [17, 31–33, 37, 44] only included patients <18 years old. In most studies [4, 5, 8, 16–21, 23–25, 27, 28, 30, 31, 33–44], the diagnosis of COVID‐19 was based on SARS‐CoV‐2 polymerase chain reaction or SARS‐CoV‐2 IgG antibody (IgG) positivity, while six studies [6, 7, 15, 22, 29, 32] additionally included patients with a strong clinical or radiological suspicion of COVID‐19.…”
