The Positive Predictive Value and Negative Predictive Value of osmole gap values ranging between -10 and 30 to identify toxic alcohol concentrations exceeding the antidotal therapy (Panel a) and hemodialysis (Panel b) thresholds
Black lines represent the positive predictive value.
Grey lines represent the negative predictive value.
- - - - osmole gap derived using equation 1 (ethanol coefficient of 1)
----- osmole gap derived using equation 2 (ethanol coefficient of 1.25)
