E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate whether there is a difference in the mean change from baseline of the blood levels of parathyroid hormone (PTH) between patients receiving cholecalciferol compared with patients receiving cholecalciferol placebo after 12 weeks’ treatment. |
Att undersöka om det finns någon skillnad i medelförändring i blodnivåer av parathormon mellan startpunkt och efter 12 veckors behandling med cholecalciferol (vitamin D) eller placebo. |
|
E.2.2 | Secondary objectives of the trial |
The following secondary variable will be assessed after 6 weeks:
• Mean change in blood levels of PTH.
Further, the following secondary variables will be assessed after 6 and 12 weeks:
• To Investigate whether there is a difference between the two treatment groups with respect to change in PTH levels after 6 weeks, and to investigate individual changes. Further to investigate differences between the two treatment in the change from baseline in musculoskeletal function and fatigue.
|
Följande sekundära variabel kommer att mätas efter 6 veckor:
* medelförändring i blodnivåer av parathormon
Följande sekundära variabler kommer att undersökas efter 6 resp. 12 veckor:
* Skillnaden mellan grupperna avseende förändring i nivåer av parathormon efter 6 veckor och även individuella skillnader.Dessutom kommer de två behandlingarna att jämföras avseende funktion hos skelettmuskulatur och trötthet efter 6 resp. 12 veckor. |
