For quantitative variables, median and range (in parenthesis) are given. GDF-15: growth differentiation factor-15; APACHE: acute physiology and chronic health evaluation; SOFA: sequential organ failure assessment. Significance between sepsis and nonsepsis patients was assessed using the Mann–Whitney U test or chi-squared test, respectively.
