Comparative effectiveness of eHealth interventions is partly limited by the extensive heterogeneity in intervention design, variation in use of eHealth tools, and expanding development of novel tools to promote weight management.
Comparing studies of the more commonly investigated biomarkers is hampered by enormous heterogeneity of study design, variation in techniques, case mix and interpretation of data.
The design strategy uses two-level factorial design for the factors that can be controlled, and blocking on the raw material to cover other non-designed variation in the raw material.
These compounds have been designed with variation in substituents, conformations of the calixarene unit and steric crowding.
Do design variations in the artificial disc influence cervical spine biomechanics?
Current studies are limited by study design, variations in operative technique and dilatation regimens, and limited follow up times.
Subsequently, design analyzes are performed to study the effects of 20 key design variations in package dimensions, material properties, and thermal cycling test conditions.
Subsequently, design analyses are performed to study the effects of 16 key design variations in package dimensions, material properties, and thermal cycling test conditions.
To analyse interactions between the manufacturing process chains, its design, variations in material properties, especially the microstructure and the resulting component properties, specimens with tension screw geometry were machined with specific varying process chains.
This lack of consistency among the published reports may be attributable to the heterogeneity of study designs, variations in PRP preparations, and differences in PRP delivery.
