Table 2 Subgroup analysis. Patients were divided into subgroups based on the following criteria: early (Stages 1–2)/ late (Stages 3-4) CKD stage, younger (under 60)/older (over 60) age, and gender so that each patient was ultimately referenced to one of eight possible different subgroups. The final trained model was implemented on each subgroup
