Description
The nih_diff_breath data element records responses to the prompt, or a congruently meaning prompt, "Shortness of breath or difficulty breathing". Equivalent prompts are: - "Shortness of breath or difficulty breathing" RADx-UP - "Shortness of breath or difficulty breathing" RADx-rad - "Shortness of breath" RADx-Tech - "Shortness of breath or difficulty breathing" RADx-DHT The values for this data element are integers that come from a list of 5 permissible integer values. The nih_diff_breath data element is the result of the harmonization of other RADx program data elements: covid_diffbreath RADx-UP; shortness_of_breath_or_dif RADx-rad; shortness_of_breath RADx-Tech; dht_diff_breath, dht_shortness_of_breath 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.
