用逐步回归法分析慢性胃炎与幽门弯曲菌感染的关系

ANALYSING THE RELATIONSHIP OF CHRONIC GASTRITIS AND HELICOBACTER PYLORI IFECTION BY STEPWISE REGRESSION

本文用逐步回归法从胃病病人的性别、年龄、香烟嗜好、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。发现慢性浅表性胃炎与慢性萎缩性胃炎都和ＨＰ感来有线性关系。

In this paper,some of factors(sex,age,age of smoking,course,hlicobacter pylori infection etc.)have been selected by stepwise regression,which are related to chronic gastritis. We find that,there exists linearrelationship not only between the chronic superficial gastritis and helicobacter phlori infection but also betweenthe chronic gastratrophia and helicobacter pylori infection.
