Prediction of the Effect of Corticosteroid on Idiopathic Nephrotic Syndrome Based on a Discriminant function1

For the purpose of discriminating between cases of nephrotic syndrome with and without corticosteroid effect, a linear discriminant function was applied in attempt to predict the effect of corticosteroid by the use of a computer. The parameters used were 15-min values of the PSP test, urinary protein, serum cholesterol, renal biospy findings, the number of red cells in the urinary sediment and immunoglobulin clearance ratio. The rate of correct prediction using the function with immunoglobulin clearance ratio was 87.0 %.
