用逐步回归法分析慢性胃炎的病因

Analysis of the Cause of Chronic Gastritis by Stepwise Regression

收集２５０名胃病患者的资料，用逐步回归法从病人的性别、年龄、嗜香烟史、病程、幽门螺旋菌（ＨＰ）感染等因素中，筛选出与慢性胃炎有关的因素，发现不仅慢性浅表性胃炎而且慢性萎缩性胃炎都和ＨＰ感染有线性关系．

In this paper, the material of 250 patients sufering with gastrosis are collected. By stepwise regression, from some factors, such as sexual distinction, age, smoking age,course and helicobactor pylon infection etc.,we have selected a few factors which are related to chronic gastritis. We find that there exists linear relationship not only between the chronic superficial gastritis and helicobacter pylon infection but also between the chronic gastratrophia and helicobacter pylon infection.
