Figure 2From: Comparison of superior vena cava and femoroiliac vein pressure according to intra-abdominal pressure Intraclass correlation coefficient according to intra-abdominal pressure cutoff. Less than 14 mmHg, agreement between FIVP and CVP measurements was excellent and better than situations when intra-abdominal pressure was >14 mmHg (0.94 versus 0.5, P = 0.002). FIVP, femoroiliac venous pressure; CVP, central venous pressure. Boxes show first and third quartiles, with the median as a thick line. Whiskers extend to 1.5 interquartile range (Q75-Q25).Back to article page
