E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The aim of this study is to investigate whether a physiologically low HC dose is better for cognition as compared to a high HC dose. |
Het doel van deze studie is het onderzoeken of een fysiologisch lage HC dosis beter is voor cognitie dan een hoge HC dosis. |
|
E.2.2 | Secondary objectives of the trial |
In addition, quality of life, metabolic profile and somatosensation will be described in relation to HC dose. |
Bovendien worden kwaliteit van leven, het metabool profiel en gevoelswaarneming beschreven in relatie tot de HC dosis. |

E.5 End points |
E.5.1 | Primary end point(s) |
Cognitive performance.
If the significance value is less than .05, there is a significant difference. This will be calculated with a paired samples t-test.
|
Cognitieve prestaties.
Indien het significante verschil kleiner is dan 0.05, is er een significant verschil. Dit zal worden berekend met een gepaarde T-toets.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
First evaluation after 4 weeks run-in phase to assess baseline functioning in patients with secundairy insufficiency.Second evaluation at the end of the study. That is after 24 weeks after initiation of the study (4 weeks run-in phase and two intervention periods of 10 weeks) |
Eerste evaluatie vindt plaats na de 4 weken durende run-in fase om een baseline bepaling te doen bij patiënten met een secundaire bijnierschorsinsufficientië. Tweede evaluatie aan het eind van de studie. Dat is 24 weken na de start van de studie (4 weken run-in fase en twee interventie perioden van 10 weken) |
