Because there is a need for one single system to avoid confusion. The single system should avoid shortcomings of other systems and include their strengths. Some grading systems are based on study design alone without explicit consideration of other important factors in determining quality of evidence. Some systems are excessively complex. An analysis of current grading systems has shown that these and other shortcomings have not been adequately addressed by any one system to date. See: How GRADE compares to other systems
