Trial Outcomes
36-Item Short Form Health Survey (SF-36)
The SF-36 is a well-established 36-item questionnaire evaluating physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. This test allows us to study the overall quality of life for those suffering from COVID-19 related OD. There is no single overall score for SF-36. The SF 36 generates 8 subscales with scores ranging from 0 (worst) to 100 (best). General health domain scores are reported here. (NCT04789499)
Timeframe: Baseline assessment
Intervention | score on a scale (Median) |

Theophylline | 75 |
Placebo | 80 |
Change in Questionnaire for Olfactory Dysfunction (QOD) From Baseline to 6 Weeks Post Intervention
Questionnaire for Olfactory Dysfunction (QOD) assesses health-related quality of life of participants based on four factors such as eating, mental health, social interactions, or fear of dysfunction.. The survey also includes questions on parosmia, a phenomena of COVID-related OD. The QOD consists of 17 statements that participants score from 0-3, resulting in a total score from 0 to 51. Higher scores reflect better olfactory-specific QOL. (NCT04789499)
Timeframe: Comparison at 6 weeks post-intervention from baseline
Intervention | score on a scale (Median) |
---|
Theophylline | 0.86 |
Placebo | 1.43 |
Olfactory Dysfunction Outcomes Rating (ODOR)
The ODOR is a 28-item QOL instrument with a total score ranging from 0 to 112 points. Higher scores indicate worse QOL with higher degree of dysfunction and limitation. A decrease of 15 or more points is deemed to be a clinically significant improvement in QOL. (NCT04789499)
Timeframe: Comparison of response rate at 6 weeks post-intervention from baseline between the 2 study groups
Intervention | score on a scale (Median) |
---|
Theophylline | -6.5 |
Placebo | -4.5 |
University of Pennsylvania Smell Identification Test (UPSIT)
"UPSIT 0-40 with higher scores indicating better smell.~This test is an objective, clinically validated 40-question forced-choice odor identification test where microencapsulated odorants on a strip are released by scratching. Out of a total of 40 points, normosmia is defined as ≥34 for males and ≥35 for females, and an increase in ≥4 points will be deemed a clinically significant improvement in symptoms." (NCT04789499)
Timeframe: Comparison at 6 weeks post-intervention from baseline
Intervention | score on a scale (Median) |
---|
Theophylline | 3 |
Placebo | 0 |
UPSIT
"UPSIT 0-40 with higher scores indicating better results.~The response rate defined as the number of participants in each group self-reporting of at least slightly better improvement in the Clinical Global Improvement Scale at 6 weeks post intervention as compared to baseline, devided by the total number of participants in that specific group. The CGI-Improvement Scale has seven response options (from 1 as Very Much Improved to 7 as Very Much Worsened) for answers to the question Compared to your sense of smell before you started the nasal irrigations, how would you rate your sense of smell now . Participants reporting 3 as Minimally Improved, 2 as Much Improved, or 1 as Very Much Improved in the CGI-I will be deemed responders to treatment, and the rate of responders will be compared between the two arms."
