ListOutcomeTime frameDescription
PrimarySF-36 physical component score (PCS)from baseline to two monthsmean change in the SF-36 (v.1) physical component score (PCS)
SecondarySymptoms scaleBaseline/Randomization weekly to 2 months, then once monthly to 6 months.
Three point Likert scale assessing how bothersome symptoms are on a weekly basis for two months then monthly until end of study, as reported by the participant: to provide a granular, detailed picture of the symptom trajectory.
SecondarySymptom ChecklistBaseline/Randomization weekly to 2 months, then once monthly to 6 months.
Symptom Checklist (adapted from the De Paul Symptom Questionnaire (DSQ2), the World Health Organization Global COVID-19 Clinical Platform's Post COVID-19 CRF and the Symptom Burden Questionnaire for Long COVID): to track symptom trajectory.
SecondarySix Minute Walking Test (6MWT) with oximetryBaseline/Randomization and 2 months
Subjects walk as far as they can in six minutes while receiving maximum encouragement. It is simple to execute, inexpensive, standardized and gives a tangible measure of functional exercise capacity. It has been validated in many different populations. The 6MWT will be conducted according to American Thoracic Society standards.
SecondaryTestMyBrain cognitive testingBaseline/Randomization to 1, 2 months 3 and 6 months
TestMyBrain was developed as a tool to collect large, population-based samples for understanding the relationship between cognition, emotion, social functioning, and health. This test battery will take about 20 minutes to complete and will assess: verbal, episodic and working memory, attention, processing speed, basic psychomotor response speed, and cognitive control.
SecondaryPost COVID19 functional status scaleBaseline/Randomization to 1, 2 months 3 and 6 months
The post-COVID-19 functional status (PCFS) scale focuses on relevant aspects of daily life during follow-up after the infection. The scale is intended to help users become aware of current functional limitations in COVID-19 patients, whether or not as a result of the specific infection, and to objectively determine this degree of disability. The scale is ordinal, has 6 steps ranging from 0 (no symptoms) to 5 (death), and covers the entire range of functional outcomes by focusing on limitations in usual duties/activities either at home or at work/study, as well as changes in lifestyle. The PCFS demonstrates good construct validity.
SecondaryReintegration to Normal Living Index (RNLI)Baseline/Randomization to 1, 2 months 3 and 6 months
This short self-administered assessment tool will determine the degree to which participants reintegrate into normal social activities such as recreation, mobility in the community and interaction in family and other relationships. This tool has been validated in community living adults with mobility limitations.
SecondaryFatigue ScaleBaseline/Randomization to 1, 2 months 3 and 6 months
The Fatigue Scale was adapted from the De Paul Symptom Questionnaire (DSQ2)'s 38 questions assessing medical history of Myalgic Encephalitis/Chronic Fatigue Syndrome (ME/CFS), comorbidities, medications, impact on quality of life and daily activities, etc.
SecondaryBrief Fatigue inventoryBaseline/Randomization to 1, 2 months 3 and 6 months
The self-administered Brief Fatigue Inventory is composed of 9 items evaluated on a 10-point scale, assessing severity of fatigue and impact of fatigue on daily life. It takes approximately 2-3 minutes to complete.
SecondaryPost-Exertional MalaiseBaseline/Randomization to 1, 2 months 3 and 6 months
The self-administered DPEMQ is comprised of three sections assessing post-exertional malaise (PEM): (i) onset and triggers of PEM (9 questions), (ii) consequences and symptoms (14 questions), (iii) duration, recovery and pacing (7 questions).
SecondaryMental Health - Post-traumatic Stress Disorder Checklist (PCL-5)Baseline/Randomization to 1, 2 months 3 and 6 months
The PCL-5 is a validated, reliable, 20-item self-report measure that assesses the 20 Diagnostic and Statistical Manual 5 (DSM-5) symptoms of Post-Traumatic Stress Disorder (PTSD). It takes approximately 5-10 minutes to complete.
SecondaryMental Health - General Anxiety Assessment Form (GAD-7)Baseline/Randomization to 1, 2 months 3 and 6 months
The GAD-7 is a valid and efficient tool for screening for generalized anxiety disorder and assessing its severity in clinical practice and research. It is an easy-to-use, self-administered patient questionnaire that can be completed in minutes.
SecondaryMental Health - Patient Health Questionnaire (PHQ-9)Baseline/Randomization to 1, 2 months 3 and 6 months
The PHQ-9 is a validated, multipurpose instrument for screening, diagnosing, monitoring and measuring the severity of depression. It incorporates Diagnostic and Statistical Manual 1V (DSM-IV) depression diagnostic criteria with other leading major depressive symptoms into a brief self-report tool. The PHQ-9 is brief and useful in clinical practice. The PHQ-9 is completed by the patient in minutes and is rapidly scored by the clinician. The PHQ-9 can also be administered repeatedly, which can reflect improvement or worsening of depression in response to treatment.
SecondaryMental Health Composite score (MCS) of the SF-36Baseline/Randomization to 1, 2 months 3 and 6 months
The self-administered SF-36 evaluates eight health concepts: physical functioning, role functioning-physical, bodily pain, general health, vitality, social functioning, role functioning-emotional, and mental health. Previous studies have used this instrument in many different populations and it takes approximately 15 minutes to complete.
SecondaryDyspneaBaseline/Randomization to 1, 2 months 3 and 6 monthsAssessed using the Borg Dyspnea scale. This short assessment tool assesses perceived shortness of breath on exertion using a 10 point scale as assessed by the patient.
SecondaryBlood samplesBaseline/Randomization and 2 months
Blood samples will be used in correlative studies using advanced multi-omic and machine learning methods to better understand our results so as to identify phenotypes that will benefit from specific therapies
