a trend towards significancep=0.071
in 2016 using a different cohort of 206 patients which demonstrated an increased mortality for those with GFR<30 mL/min/1.73 m 2 [HR 4.322, CI: 1.855–10.069, p=0.001] and only a trend towards significance for those with GFR 30-60 mL/min/1.73 m 2 [HR 1.868, CI: 0.949–3.679, p=0.071], with the latter likely underpowered to assess mortality among this subset of patients [ 19 ].
