“…The studies on diabetic nephropathy described essentially the same phenomenon: change in albuminuria, but measured and reported with different techniques, namely arithmetic mean (reported or derived [ 52 ]) as micrograms per minute or milligrams per day or milligrams per 24 h or micrograms per milligram creatinine [ 45 , 73 – 78 , 80 – 83 , 85 – 88 , 91 , 94 , 96 , 98 , 101 – 103 , 105 ], geometric mean [ 79 , 84 , 89 , 95 , 100 ], geometric mean of percentage change [ 90 , 93 , 104 ], rate of change in micrograms per milligram per year [ 99 ], or therapeutic success defined in different ways [ 92 , 97 ]. Geometric means, reported with the asymmetric 95% CI, had to be logarithmically transformed to estimate the symmetric standard deviation.…”
