Abstract
The precision of death time estimation by vitreous potassium using 5 different formulas is compared on a random sample of 600 cases. Mean differences, standard deviations and 95% limits of confidence between real and extrapolated time since death were calculated. The best results were obtained using equations with "mean" slopes of about 0,17 or 0,19mmol/l per hour. Equations with a steeper or flatter slope reveal already great mean deviations between real and extrapolated time since death and do not allow a reliable death time estimation. Copyright ÂEntities:
