ABSTRACT
This is a preliminary report using APPLE I type microcomputer to diagnose the nature of intra-cranial tumor (ICT). A computer program was made. All clinical data of 520 cases of intracranial tumors proved by operation and pathology were put into the computer for analysis. The cases were di vided into two groups: the 1st 120 cases were used to make a stepwise regression analysis to get a multiple linear regression equation; and the 2nd 400 cases were tested to prove the reliability of the e quation and diagnose the nature of ICT. The reliability was 85.6%.From the preliminary study, the formula that was derived for clinical purpose to evaluate the nature of ICT depends upon 7 dependent variables. It may be a supplement to evaluate the nature of ICT in early stage.
