为了对我院烧伤治疗效果作出评价,我们查阅了近八年(1979～1986)和既往十八年(1961～1978)的全部病历,获得完整资料共1002例(其中近八年为570例),分以上两个年代组进行对照分析。分析方法及结果一、生存率概率单位分析: 将两个年代组患者分别以烧伤总面积(TBS)和Ⅲ°面积(Ⅲ°A)分组,组距10。以TBS和Ⅲ°A各组的均数作自变量x,相应的生存率概率单位作应变量y,求出各自的回归方程、生存率为50％的预计面积(LA50)及其95％的可信限(表1)。根据回归方程作回归直线图1、2;复将生存率概率单
In order to evaluate the effect of burn treatment in our hospital, we reviewed all medical records in the past eight years (1979-1986) and the past eighteen years (1961-1978), and obtained 1002 cases of complete data (including 570 cases in the past eight years). , divided into the above two groups of time for comparative analysis. Analysis methods and results 1. Probability unit analysis of survival rate: Patients in the two age groups were divided into total burn area (TBS) and III° area (III°A) with a group distance of 10. Taking the mean of each group of TBS and III°A as the independent variable x, and the corresponding survival probability unit as the dependent variable y, find the respective regression equation, the estimated area (LA50) with a survival rate of 50% and its 95% Confidence limits (Table 1). According to the regression equation for the regression line diagram 1,2; complex survival probability single
