Correlation between plasma Gas6 concentration and SOFA score. (a) SOFA scores were separated into quartiles and plotted against Gas6 plasma concentration. Groups were compared using the Mann-Whitney U test. (b) Individual SOFA scores were plotted against Gas6 concentration and the correlation was evaluated using the Spearman test (rs = 0.37, P = 0.01). Gas6, growth arrest-specific gene 6 product; SOFA, Sepsis-related Organ Failure Assessment.
