Correction to: Scientific Reports https://doi.org/10.1038/s41598-017-12645-4, published online 04 October 2017.
This Article contains errors in the results of the Full Age Spectrum (FAS)(crea/cys). For the original calculation of mean bias, SD of differences, P10 and P30 value as well as Bland Altman in Figure 3 the rescaling factor for Serum creatinine (Scr) was switched for females and males.
As a result, in the Results section, under subheading ‘Performance of BTP based estimating equations and comparison with established equations’,
“All in all the BIS2 showed the best performance, which is not surprising since it was developed from the BIS dataset, and the FAS was relatively equal to Inker(BTP) and superior to CKD-EPI(Crea/CysC).”
should read:
“All in all the BIS2 showed the best performance, which is not surprising since it was developed from the BIS dataset, and the FAS(crea/cys) was relatively equal to BIS2 and superior to Inker(BTP) and ECD-EPI(crea/cysc).”
In addition, the correct Table 3, showing the correct details for the FAS(Crea/Cys) row, is shown below as Table 1.
Finally, the correct Figure 3, containing the correct Bland-Altman plot for FAS(Crea/Cys) in panel b, appears below as Figure 1.
(a) Bland and Altman of BTP-based eGFR-equations versus mGFR. (b) Bland and Altman of creatinine-/cystatin C-based eGFR-equations versus mGFR. (a) and (b) Bland and Altman plots of BTP-based and combined creatinine/cystatin C-based eGFR-equations versus mGFR (n = 566). The bias is represented by the dashed middle line. The horizontal grey bar represents the area between the upper and lower limits of the interval of agreement. mGFR = measured glomerular filtration rate; eGFR = estimated glomerular filtration rate; BIS = Berlin Initiative Study; CKD-Epi = Chronic Kidney Disease Epidemiology Collaboration, FAS = Full Age Spectrum. For details about the GFR estimating equations please refer to the material section.
