The authors apologize for the mistakes in the Results section. In Table 4, sex, current or ex-smoker, current or ex-drinker, hypercholesterolemia, diabetes mellitus, history of CVD, and antihypertensive medication should have been treated as binary variables coded as 1 or 0. However, the authors used the binary variables divided by 1-standard deviation. This error caused an underestimation of the hazard ratios of the binary variables. For example, the standard deviation of sex (men=1 and women=0) was calculated as 0.47, although it is an inappropriate calculation. Thus, the correct hazard ratio of men is calculated as follows: 0.80 [the value before correction](1/0.47)=0.62 [after correction]. All corrections are shown below.

We calculated the HR (95% CI) for CKD development per 1-SD increase in age, BMI, SBP, baseline eGFR, and lnNT-proBNP. For binary variables, the hazard ratio of code “1” (vs. “0”) is indicated. Abbreviations as in Table 1.
