title: Precision of estimating the time since death by vitreous potassium--comparison of two different equations.
abstract: The precision of death time estimation by vitreous potassium using two different formulas [1-3] is compared on an independent random sample of 100 cases. The very flat slope in Sturner's equation is the reason for a systematic overestimation of the time since death with much wider 95%-limits of confidence compared to the results using an own equation with a steeper slope of vitreous potassium.
