Single-field queries use only 1 API field, whereas multifield queries use 2 or more API fields. The ENRs required to complete a query is based on the limitations of the MAUDE API (see Supplementary S2, http://links.lww.com/JPS/A624). A single device category implies that the device under investigation falls into one specific category. In contrast, multiple device categories indicate that the device pertains to several categories. The term “presence of data processing flow” denotes whether the article describes the methods used to handle the MDRs retrieved through these queries.
