Main characteristics of the included studies.

*In this study, nephrotoxicity was not defined by the investigators. For the purpose of our study, we considered as nephrotoxicity the number of patients who had ≥1.5 times baseline creatinine serum concentration. The number of patients with hypokalaemia was not added, because many of them may have been also included in those with elevated serum concentration creatinine.
