We would like to focus on the varied approach and lack of consensus in defining early and late initiation of RRT, as all of the 15 studies quote different definitions in their methods. Even those utilising similar markers and criteria for AKI - for example, the RIFLE criteria [
2] (two studies) or blood urea and nitrogen (four studies) - utilised and interpreted them in very different ways when distinguishing early and late initiation of RRT. …
