Similar risk for hemangiomas after amniocentesis and transabdominal chorionic villus sampling [PDF]
Aim: In an earlier study we have shown that transcervical chorionic villus sampling in excess of 90 mg increases the risk for hemangiomas of infancy three- to four-fold compared to amniocentesis.

A general method to determine sampling windows for nonlinear mixed effects models with an application to population pharmacokinetic studies [PDF]
Optimal design methods have been proposed to determine the best sampling times when sparse blood sampling is required in clinical pharmacokinetic studies. However, the optimal blood sampling time points may not be feasible in clinical practice.

Simulation Studies for Complex Sampling Designs
Choosing the appropriate variance estimation method in complex surveys is a difficult task since there exist a variety of techniques which usually cannot be compared mathematically. A relatively easy way to accomplish such a comparison is on the basis of
