Dotted line, mean difference (bias); solid lines, limits of agreement (bias ± 1.96 SD).
Additionally, bias (median difference between pPU and measured 24hU-PU), precision (IQR and P25, P75 of differences between pPU method and measured 24hU-PU), accuracy (absolute number and percentage of pPU values that lied within range 15%% (P15), and/or 30%% range of measured 24hU-PU (P30) were calculated.
Bias was defined as the median difference and the median absolute difference as well.
The median difference between measured and estimated sodium excretion was used to calculate the bias.
Given that the observed median difference in expression of significant genes between populations was 2.7-fold, the contribution of mapping bias to the observed expression differences is expected to be negligible.
However, the median difference of RBF network estimates from sGFR was greater than those from the other two estimates, indicating greater bias.
In the subgroup with sGFR <30 mL/min/1.73 m, the bias of Chinese formula 2 was more than those of the Thai formula and Asian formula (median difference, P < 0.001 for both comparisons), while it was less than those of Chinese formula 1, the Japanese formula, and the Korean formula (median difference, P < 0.001 for all comparisons).
The median difference between measured CrCl and the prediction method of excretory kidney function was lowest for the BCM based model mCrCl (bias = 0, absolute bias = 4.4, IQR = 7.9 mL/min/1.73 m).
Among region, the median difference is only 3pt.
The median difference is <18% for the annual maximum rainfall values ⩽50 mm.
