How this corrected browser works

The main view uses only classifications where classification.disorder_id > 0, which gives the top two levels: broad disorder group and second-level classification heading. The separate audit view shows disorder_id = 0 rows, which appear to be unassigned or lower-level headings and should not be mixed into the main disease classification structure.
