If there have been authors from numerous countries, the nation of origin was determined working with the country that the corresponding author belonged to. Those in the similar nation had been classified into those from 1 institute and those from a lot more than one institute. Articles that received funding source were identified. Degree of evidence for clinical studies was also identified, 2 and was evaluated based on the levels of evidence introductory document in the Oxford Centre for Evidence-based Medicine.19 In addition, journal name and IF have been also extracted. The journals IFs title= zookeys.482.8453 have been crossreferenced using the 2014 edition of Journal Citation Reports ( JCR): Science Edition (1945?014). Evaluating the included research Based on included study style, analysis setting and objectives, the selected articles were grouped into five categories: clinical recommendations, overview, meta-analysis, basic analysis and clinical investigation (which includes observational and randomised handle trials, RCTs). Prospective, retrospective and case series had been all categorised as observational studies. RCTs consist of both single-blind and double-blind research. Furthermore, as outlined by the causes of AKI, the subjects have been divided into (1) any bring about, (two) contrast, (3) cardiac surgery and (4) other people. Due to the fact some articles have been cited more often than others as a result of the distinction in time considering that publication, this error was adjusted by a citation index determined for each and every article. The citation index was defined as the mean variety of citations per year. For comparison, we searched Scopus (http://www. scopus.com/ search/form.url; retrieved on 15 July 2015) for total citation counts on the T100 title= 00480169.2014.963792 articles. Statistical evaluation Information are represented as median or IQR. The variations in between groups were evaluated by the Wilcoxon rank-sum test. The Spearman test was employed to evaluate the strength and path in the linear relationship among journal IF as well as the quantity of T100 cited articles or citations, as well as the correlation of short article citations among different databases (Net of Science Core Collection and Scopus). All information analyses had been performed with SPSS V.17 application (SPSS, Chicago, Illinois, USA). All probability values have been two-tailed, as well as the threshold for significance was set at p
