Association between selenium biomarkers and organ injury. Correlation matrix of selenium biomarkers and continuous clinical (outcome) parameters at baseline (BL), admission to the intensive care unit (ICU) and postoperative day one. Positive associations are shown in red, inverse associations in blue. The strength of the relationship is depicted by color graduation. Two values specify each correlation: Spearman’s rho in the upper row and the p value in the lower row. Only significant p values and trends are shown. No relations were observed in the blank fields. The datasets are different in size for each biomarker, with selenium having the most pairs and GPx3 having the fewest. Overall, the associations were weak to moderate. It is important to note that these correlations do not imply causation. PODS persistent organ dysfunction and death, SOFA sequential organ failure assessment, SF 36 short-form 36 questionnaire
