Plasma Levels of Aminothiols, Nitrite, Nitrate, and Malondialdehyde in Myelodysplastic Syndromes in the Context of Clinical Outcomes and as a Consequence of Iron Overload

Table 4

Oxidative stress parameters in the control group (0) and four myelodysplastic syndromes subgroups (1–4). Values are shown as means ± SD. Data were analyzed by ANOVA, and P values are shown for significantly differing parameters.
