^a Gap is left in the next ranking number when specific institutes are given the same number
^b The variance between the 15.45% mentioned in the text and the sum of 21.52% in Table 2 can be attributed to overlapping research productivity among institutions. This overlap occurs when researchers from different institutions collaborate on research projects, resulting in the same research output being attributed to multiple institutions
