4 August 2023	New search has been performed	We added 2 new trials (Bharathan 2016; Bosch 2000), and obtained further information from an abstract that the previous authors used (as the full text was published subsequently, Bärthel 2012). Cavalcanti 2011 had used data from 9 trials for their meta‐analysis (10 trials for this systematic review). We identified 1 ongoing trial that has not started recruiting.
4 August 2023	New citation required and conclusions have changed	Apart from confirming the findings of Cavalcanti 2011, after adding more participant data, we also found uncertain effects on early allograft dysfunction and adverse events (serious and non‐serious). Our methodology was more robust, including a Trial Sequential Analysis, and we provided a diversity‐adjusted required information size for the question explored.
