Fig 1 Relationship between hypovolaemia score and its theoretical probability. Probability=1/(e–T/100+1); Score=100 Ln [probability/(1–probability)]. British Journal of Anaesthesia 2001 86, 754-762DOI: (10.1093/bja/86.6.754) Copyright © 2001 British Journal of Anaesthesia Terms and Conditions
Fig 2 Observed and expected (predicted) rates of hypovolaemia status in test data set (30 ICU patients). A perfect predictor would exactly coincide with the diagonal line running from bottom left to top right (line of identity). As values of Z statistic lie within the range –2 to +2, the fit of the predictor to the line of identity is satisfactory. Predictions are therefore reliable.
