Previous investigators have reported significant elevations of serum copper and ceruloplasmin levels in lymphoma patients and subjects using estrogen, but have not taken into account the smoking habits of these populations. In order to determine whether smoking had any effect on these variables, the authors examined five groups for serum and erythrocytic copper and ceruloplasmin levels: 40 healthy subjects, 14 users of oral contraceptives, 25 smokers, 14 nonsmoking pretreatment lymphoma patients, and eight treated lymphoma patients. Significant elevations of serum copper and ceruloplasmin in pretreatment lymphoma patients, treated patients, and estrogen users were found, confirming previous reports. In addition, all groups had elevations of erythrocytic copper compared with the healthy subjects. Also, significant elevations of serum copper (P less than .0053) and ceruloplasmin (P less than .0001) were found in smoking relative to nonsmoking subjects. No correlation between duration of smoking and these elevations was found.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
