In academia, research is utilized as an indispensable tool for either discovering or inventing new knowledge or modifying the current knowledge of the academic discipline. Numerous types of research designs are used in the academic research and each design has its own advantages and disadvantages [1]. How much a particular research design contributes to the ultimate aim of research (i.e. finding new knowledge or modifying the current knowledge) determines the superiority of that research design in comparison to others. A technique that ranks the research designs based on their contribution to the advancement of knowledge or the modification of the current knowledge is known as the hierarchy of evidence. Hierarchy of evidence is defined as a technique to ranks the study or research designs on the basis of the relative strength of their results or evidence [2,3].
