The number of observations, mean and standard deviation for each group and the pooled p-value for mean differences for each variable. (^∗) Study group is the confirmed CKD patients in the registry with use-able complete observations. (^∗∗) The remaining confirmed CKD patients in the registry (as defined by at least one eGFR calculated and max{eGFR} ≤ 60 ml/min/1.73 m ²).
