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.
摘要
在100例独立随机样本中，比较了使用两种不同公式[1-3]通过玻璃体液钾估计死亡时间的精度。与使用玻璃体液钾斜率更陡的自身公式得到的结果相比，Sturner方程中非常平缓的斜率是导致死亡时间系统性高估的原因，其95%置信区间更宽。
