Trials are sometimes recorded in more than one registry. These records can refer to each other using the 'Secondary ID' field. The search portal uses these Secondary IDs to group records about the same trial together in the search results.
Each group of records referring to a trial is displayed in table that is seen by pressing the + symbol. The record with the earliest date of registration is always shown first.
