Renalase levels were higher at baseline in patients with CKD progression during follow-up (median 80.40 vs. 51.79, p = 0.001), in patients with hospitalizations (median: 81.43 vs. 53.86, p = 0.001) and in patients who died (median: 95.20 vs. 60.22, p = 0.022) (Table 5). Here, RNLS is linked to chronic kidney disease.
