2. Numbers smaller than five have been suppressed in line with DASA Health Information's rounding policy. Suppressed numbers are represented as ~ and
    where there is only one number smaller than five in any column the next smallest number has also been suppressed. This may include numbers larger than
    five.
3. Figures have been revised due to Reservists being removed and/or new medical information becoming available and therefore changing the cause code
    category.
4. Figures include medical discharges for which either no medical documents have been received by DASA or consent for DASA to analyse individual medical
