Who will be blinded
cognitive difficulties
BLIND
The statistician will be blind to the content of the intervention arm that will be called “A” and “B”. The neuropsychologists who perform the baseline assessment do not know about the randomisation (which is only carried out after the visits). The neuropsychologists that will be in charge of follow-up will also be blinded to the arm of the intervention. Patients will be warned to not mention their intervention arm or provide information that could cue the clinician (this will be reminded before each assessment session). If the clinician becomes unblinded during the testing session, this will be reported in the eCRF.The person administering the intervention cannot be blinded, as the content is different. The participants cannot be blinded. However, the trial will be presented as “assessing the positive effect of two interventions on post-covid cognitive difficulties” Our prediction (superiority of the cognitive intervention) will not be communicated to the participants until the end of the trial (last follow-up for the last participant included).
