  1. The 48 patients who did not complete biochemical profiling in our laboratory in the last 3 months were older and had a higher Charlson index, but with similar creatinine, e-GFR, and diet history as compared to the whole on-diet population, thus confirming the advantage of tailoring the check-ups also considering the patient’s needs
