Fig. 3From: Impact of HIV infection on the presentation, outcome and host response in patients admitted to the intensive care unit with sepsis; a case control studyEndothelial cell activation markers in matched patients with pneumonia stratified according to HIV infection status. Plasma levels of soluble E-selectin, soluble intercellular adhesion molecule-1 (ICAM-1), angiopoietin-1 and angiopoietin-2 on days 0, 2 and 4 after intensive care unit admission. Data in box-and-whisker diagrams depict the median and lower quartile, upper quartile and the respective 1.5 IQR as whiskers (as specified by Tukey). Dashed lines represent median levels in 27 healthy volunteers. P values are indicated for differences between HIV-positive and HIV-negative patients at each time pointBack to article page
