Abstract:
Objective To discuss the clinical application of polynomial curves fitting.Methods Based on the experiments of TBIL, ALT, DBIL and Cr,the linear experimental data were polynomial fitted.Results The optimal polynomial of TBIL is y=-3.886+7.544x , and the evaluation is linear 1; The optimal polynomial of ALT is y=5.293+25.897x-0.043 x~2, and the evaluation is linear 2;The optimal polynomial of DBIL is y=-2.950+1.688x+0.011x~2, and it′s non-linear; The optimum polynomial of Cr is y=11.654+14.512x-0.010 x~2, and the evaluation is inexactitude.Conclusion The polynomial fitting curve is the perfect linear evaluation method. It guarantees both the accuracy and reliability of the experimental results, and is more suitable to clinic.
