Log transformation was applied to this factor before including in regression model. Note: Pseudo R2 = 16.68%; constant (Y-intercept) = 0.0000153; change in Pseudo R2 is an incremental increase in Pseudo R2 resulting from adding variable to model last. ALT: Alanine aminotransferase; HbA1c: Glycated hemoglobin.
