These factors have worse scores on the scales that measure the patient's clinical status, especially on the SOFA and Apache II scales; and SAPS II, differences in analytical parameters (lower hematocrit, Hb, fibrinogen, and arterial pH, and higher blood glucose and potassium levels), and the greater presence of kidney failure in transfused patients compared to non-transfused patients. Here, GSTM1 is linked to kidney failure.
