| Description | The nih_no_sympt data element records responses to the prompt, or a congruently meaning prompt, "None of the above". Equivalent prompts are:
- "None of the above" RADx-Tech
- "None of the above" RADx-DHT
The values for this data element are integers that come from a list of 5 permissible integer values.
The nih_no_sympt data element is the result of the harmonization of other RADx program data elements: no_symptoms RADx-Tech; dht_no_symp RADx-DHT
Note that the meaning of the value 97 is context specific and depends on the subset of permissible value used by a specific study (not all studies presented the full set of permissible values documented here for this data element). Therefore, the meaning of the value 97 in an individual data record MUST be determined by referring to the original data dictionary for the non-harmonized data in that study.
