Table 7. Comparative analysis of the results achieved in patients of the two studied groups in the third tertile (T3) (64-79 years of age) for the two-year follow-up period (2020 and 2021).
Qo (l): convective volume; IDH (%): intradialytic hypotension; RT (h): recovery time; spKt/V: single-pool Kt/V, dialysis adequacy index; URR%: urea reduction ratio, dialysis adequacy index; nPCR (g/kg/d): normalized protein catabolic rate; Alb (g/l): serum albumin; Hgb (g/l): hemoglobin; ESA (UI/week): erythropoietin stimulating agent
