The Editor-in-Chief has retracted this article (Joviæ et al. 2019) because validity of the content of this article cannot be verified. This article showed the evidence of substantial text overlap [most notably with the articles cited (Petkovic et al. 2016; Mladenovic et al. 2016)] and authorship manipulation. All authors disagree about this retraction.
