Each patient characteristic was analyzed separately. The coefficients indicate the difference in mean kidney length (millimeter). For the categorical variables, this difference is correlated with the presence or absence of the characteristic. For the continuous variables, this difference is correlated with a one unit increase of the variable. Model 1: each patient characteristic was adjusted for age and sex. Model 2: each patient characteristic was adjusted for age, sex, and eGFR. 95% CI, 95% confidence interval; —, no change in coefficients because the model already included eGFR; HbA1c, hemoglobin A1c.
