Fig. 3From: Organ system network analysis and biological stability in critically ill patientsStability of multiple organ system clusters evaluated by dispersion of principal component scores. White circles indicate medians, and black boxes indicate interquartile ranges of principal component scores for a the respiratory-renal-inflammatory cluster and b the cardiovascular-hepatic-coagulation cluster. Kernel density estimations are shown on the side of the boxes (gray area). Dispersion of the scores for the respiratory-renal-inflammatory cluster in the non-survivors is not significantly different than those for the total survivors and the matched survivors. However, the dispersion of the scores for the cardiovascular-hepatic-coagulation cluster in the non-survivors is significantly different than that for the survivors. NS, not significant with a Cohen’s d ≤ 0.2 (not available for the Ansari-Bradley test). *Difference in medians of principal component scores with a P < 0.001. **Statistical variability in the non-survivors evaluated by the Ansari-Bradley test compared to the total survivors (P = 0.002) and the matched survivors (P = 0.004). ***Deviation from 0 in the non-survivors compared to the total survivors (P = 0.003) and the matched survivors (P = 0.003)Back to article page
