Predicting average IGF-1 SDS and average IGF-1 concentrations with samples on Days 2.5 and 5.0. (a) The method to predict average IGF-1 SDS using an IGF-1 SDS reading at a time since the last dose was as follows: for an IGF-1 sample drawn 2.5 days post-dose, subtract 0.68 SDS from the measured value; for an IGF-1 sample drawn 5 days post-dose, add 0.39 to the measured value (b) The method to predict the average IGF-1 concentration using an IGF-1 concentration reading at a time since last dose is as follows: for an IGF-1 sample drawn 2.5 days post-dose, divide the sample concentration by the ratio of 1.25; for an IGF-1 sample drawn 5 days post-dose, divide the sample concentration by the ratio of 0.87.
