“…11 of them were excluded from the full-length review as they did not report the outcome of interest while 5 articles were excluded because they were not observational studies. Six studies [9,10,11,12,13,14] were subsequently excluded because they did not use standard AKI definitions of Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease (RIFLE), Acute Kidney Injury Network (AKIN), and Kidney Disease: Improving Global Outcomes (KDIGO) classifications. Thus, 17 cohort studies [18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,37] comprising 24,158 patients undergoing THA were included into the meta-analysis of associated AKI incidence.…”
