The nih_walk_climb data element records responses to the prompt, or a congruently meaning prompt, "Do you have serious difficulty walking or climbing stairs?". Equivalent prompts are: - "Do you have serious difficulty walking or climbing stairs? (5 years of age or older)" RADx-UP - "Do you have serious difficulty walking or climbing stairs?" RADx-rad - "Do you have serious difficulty walking or climbing stairs? (5 years or older)" RADx-Tech - "Do you have serious difficulty walking or climbing stairs?" RADx-DHT The values for this data element are integers that come from a list of 5 permissible integer values. The nih_walk_climb data element is the result of the harmonization of other RADx program data elements: disability_walking RADx-UP; walking_climbing_dis RADx-rad; walk_stairs RADx-Tech; dht_walk_climb 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.
