为了探讨年龄因素与结直肠癌发生之间量的关系 ,我们建立了年龄与结直肠癌发病例数关系的数学模型为： f(x)=3.188－ 0.9425x＋ 0.0619x2－ 0.0006x3,并对其进行了假设检验及分析 ,现报告如下。 1.临床资料：选取南方医院 1975～ 1999年间手术的全部结直肠恶性肿瘤病例共 1
To investigate the relationship between age and the amount of colorectal cancer, we established a mathematical model for the relationship between age and the number of cases of colorectal cancer: f(x)=3.188-0.9425x+ 0.0619x2- 0.0006x3, and Hypothesis testing and analysis were performed. The report is as follows. 1. Clinical data: A total of 1 cases of colorectal malignancies were selected from the Southern Hospital between 1975 and 1999.
