Table 2. Data underpinning measurement of effectiveness of Mates in Construction.

QLD pre-MIC period	Number of suicide deaths	Construction industry workforce	QLD post-MIC period	Number of suicide deaths	Construction industry workforce
Note. QLD = Queensland. NSW = New South Wales. MIC = Mates in Construction. RRR = relative risk ratio. Est. = estimated.
