Note: ▲ Authors conclude there is an association between high TTV‐load and the outcome. ▼ Authors conclude there is an association between low TTV‐load and the outcome. =Authors conclude there is no association.

^{^a}

Tx: transplantation, LuTx: lung transplantation, KTx: kidney transplantation, LiTx: liver transplantation.

^{^b}

Reported sample size. Actual sample size in the analyses may be different.

^{^c}

Whether the association between TTV‐loads and the outcome (meaningfully) exists according to authors.

^{^d}

n.m.: not mentioned.
