1991 Format For Patient Micro Data Tape

    This section consists of a detailed breakdown of data tape
    record, providing a brief description of each item of data
    included in the records.  The data are arranged sequentially
    according to their physical location on the tape record. Unless
    otherwise stated in the "item description" column, the data are
    derived from the Patient Record Form (page 7).  The AMA and the
    induction interview (reference 3) are alternate sources of data,
    while the computer generates other items by recoding selected
    data items.
