Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Establishment of a (quantitative) relationship between diffuse reflectance NIR spectroscopy measurements on the skin (both positively and negatively correlated wavelengths) with the body fluid balance using a limited set of research subjects. Body weight will be used as reference for the body fluid balance. BIA will be used as a second line control. This pilot study will generate detailed information needed to verify the suitability of protocols and methods in order to develop the final protocol for a subsequent main study. | — |
