平行設(shè)計下的生物等效性如何評價? 已有2人參與
|
|
目前教科書上公式都是基于交叉實驗的,那么平行實驗設(shè)計下的生物等效性有什么公式評價沒?交叉實驗都是同一個受試者的兩種制劑效應(yīng)值比較,然后再統(tǒng)計,那么平行實驗下的數(shù)據(jù)應(yīng)該如何處理呢? [ 發(fā)自手機版 http://www.gaoyang168.com/3g ] |

Statistical evaluation of a parallel group design - confidence interval A parallel design with two products (T with nT subjects and R with nR subjects) can be analysed, after loge-transformation, using the 90% c.i. of the ratio (T/R) of the means of the test product to the reference product (4,6). The 90% c.i. of the ratio (T/R) is given by (eL, eU), where L=(lnT -lnR)-t 100,nT +nR-2 *v'{s2( linT + I/nR)) and U=(lnT-lnR)+t I0%,nT+nR_2 *v'(s2(l/nT + I/nR))· InT and InR are the means on the loge-transformed data, S2 = [(nT-l)s/+(nR-l)sR 2] I (nT+nR-2) , ~2 and SR 2 are the variances for the test and reference poducts, respectively. 文獻Statistical aspects of bioequivalence testing between two medicinal products(2005) |
