Box plots of plasma mitochondrial DNA concentration in trauma patients stratified by the severity of injury.

<p>Plasma mtDNA concentrations presented as median values (line across the boxes), IQR (limits of the boxes), and 5^th to 95^th percentiles (whiskers). Plasma mtDNA concentrations in traumatic patients with ISS ≧ 16 were significantly higher than in patients with ISS < 16 (P<0.001).
