Yoshida Y, Kashiwabara K, Hirakawa Y, et al. Conditions, pathogenesis, and progression of diabetic kidney disease and early decliner in Japan. BMJ Open Diab Res Care 2020;8:e000902. doi: 10.1136/bmjdrc-2019-000902

This article was previously published with an error.

  1. The formula for predicting the rate of lowering speed of eGFR at T years later in trajectory analysis was incorrect (Results, P6, line 3).

    In the actual data, T was calculated as a value of 1 (baseline) to 5 instead of 0 to 4.

    Correct: 3.5×(T+1)–16

    Incorrect: 3.5×T–16

  2. The eGFR value 4 years after from baseline of the early decliner predicted by trajectory analysis was incorrect (Discussion, P7, line 14).

    The formula predicted by trajectory analysis for predicted eGFR after T years is below (not shown in manuscript):

    F(T+1)= 13.560539 − 15.968622*(T+1)+1.767836*(T+1)2

    The eGFR value after 4 years is derived to be −22 mL/min/1.73 m2, which is in agreement with the results shown in the figure 2 (P5).

    Correct: −22 mL/min/1.73 m2

    Incorrect: −29 mL/min/1.73 m2
