RADx Variable CategoryRADx Core Variable
Description
The nih_copd data element records responses to the prompt, or a congruently meaning prompt, "Chronic obstructive pulmonary disease (COPD)". Equivalent prompts are: - "Chronic obstructive pulmonary disease (COPD)" RADx-UP - "Chronic obstructive pulmonary disease (COPD)" RADx-DHT The values for this data element are integers that come from a list of 5 permissible integer values. The nih_copd data element is the result of the harmonization of other RADx program data elements: cc_copd RADx-UP; dht_copd 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.
