This oid is used as an identifier II.root to indicate the the extension is an absolute URI (technically, an IRI). Typically, this is used for OIDs and GUIDs. Note that when this OID is used with OIDs and GUIDs, the II.extension should start with urn:oid or urn:uuid: 

Note that this OID is created to aid with interconversion between CDA and FHIR - FHIR uses urn:ietf:rfc:3986 as equivalent to this OID. URIs as identifiers appear more commonly in FHIR.

Effective treatment for patients with the novel Coronavirus Disease (COVID-19) is desperately needed and is under rigorous research. Nigella sativa oil (NSO), a herbal medicine, that has a documented wide antiviral and immunomodulatory activities offering a therapeutic potential for COVID-19.</p>
<p>Methods
Adult symptomatic patients with mild COVID-19 were recruited between May and August 2020 from King Abdulaziz University Hospital in Jeddah, Saudi Arabia. They were randomly assigned to receive supplementation with oral capsules of NSO (MARNYS® Cuminmar 500 mg twice daily for 10 days) plus standard of care or standard of care medications alone. The primary endpoint was the proportion of patients recovered (free of symptoms for 3 days) within 14 days after randomization. This trial was registered with clinicaltrials.gov, NCT04401202.</p>
<p>Findings
A total of 94 patients were enrolled. Their mean age was 35 (SD=11) years old and 57% of them were male. There were 47 patients in the treatment group (NSO) and 47 patients in the control group. The proportion of patients recovered in the treatment group was significantly higher than the control group, 37 (79%) versus 21 (45%) (p=0.001). Additionally, there was a significant difference in the average recovery time among both groups, 9 (SD=3) versus 11 (SD=3) days (p=0.003). Furthermore, 2 patients from the control group required hospitalization within the study period versus none in the treatment group. Adverse events were reported in 3 patients of NSO recipients as gastrointestinal symptoms.</p>
<p>Conclusions
In this RCT of adult patients with mild COVID-19, NSO was associated with a significant increase in the likelihood of recovery and a decrease in the likelihood of hospitalization. To our knowledge, this is the first RCT that shows potential therapeutic benefits of NSO in patients with COVID-19 which requires further confirmation with larger double-blinded RCTs.</p>
