almost reached significanceP = 0.0559
There was a negative correlation between U-α1/cr and both tKV and rKV in singletons (r = − 0.44, CI − 0.64 to − 0.19, P = 0.0014 and r = − 0.40, CI − 0.61 to − 0.14, P = 0.0041), small negative correlation with eGFR almost reached significance (r = –0.27, P = 0.0559).
