[Studies on background of gamma-GTP abnormality in human multiphasic screening. (Part 3): Multiple regression analysis by SAS statistic package for computer analysis].

Multiple regression analysis in 1493 cases (1256 male cases, 237 female cases) who were examined in the short-term human dry dock managed by the Fukuoka University Hospital, was done with gamma-GTP as the dependent variable and other parameters as the independent variables. As the result, 16 variables including LAP, alcohol, GPT, triglyceride, HDL and obesity rate were selected as the variables explaining gamma-GTP by stepwise methods in men. The standard regression coefficient of alcohol is shown to be greater than that of obesity on gamma-GTP. On the contrary, neither alcohol nor the obesity rate was included in this regression formula in women.
