Fig. 2From: Serum levels of protein carbonyl, a marker of oxidative stress, are associated with overhydration, sarcopenia and mortality in hemodialysis patientsBox plots showing the difference in serum protein carbonyl levels according to volume status and muscle strength. The black lines in the box show the median values of the groups. The patients with overhydration and low HGS had significantly higher levels of serum protein carbonyl.
