本文目的在于找寻重症急性肝功能衰竭的预后因素。作者假设重症急性肝功能衰竭的死亡和治愈病例在演变过程中的表现有所不同,对36例死亡者和9例治愈者用等级分类法逐项对比各项参数,得出了可表示预后良好的两组指标。每一指标按N_1-N_2/N_1+N_2公式计算其可信系数(N_1:病程演变符合该项指标预示的结果的例数;N_2:预示不正确的例数。如某项指标预示完全正确,其可信系数为1;如只有50％正确者,可
This article aims to find prognostic factors for severe acute liver failure. The authors hypothesized that the death and cure cases of severe acute liver failure differed in their evolution, with 36 patients who died and 9 who healed by item-by-item comparison of the parameters, yielding a good prognosis Two sets of indicators. For each indicator, its credible coefficient is calculated according to the formula N_1-N_2 / N_1 + N_2 (N_1: the number of cases in which the course of disease evolves in line with the result indicated by the indicator; N_2: the number of cases indicating an incorrect case, Its credible factor is 1; if only 50% is correct, it can be
