*Missing: Of 1,471,600 encounters in total, the numbers of missing for each group were as follows: sex 13,262, age 12,385, Non-English speaking background 142,171, Indigenous status 236,818, and ASGS 39,140. Of 3181 encounters where TE was managed, the numbers of missing for each group were as follows: sex 24, age 22, NESB 313; Indigenous status 543; and ASGS 87.
^Example: As an example, of 198,900 encounters with patients aged 45–54 years, the likelihood that TE was managed at any one of these encounters was 0.59% (95% CI: 0.55–0.62); i.e. TE was managed at approximately 6 per 1000 encounters with patients aged 45–54 years.
