  1. OR = odds ratio. RRMA = Rural, Remote and Metropolitan Areas classification. SEIFA = Socio-Economic Indexes for Areas. IRSD = Index of Relative Socio-Economic Disadvantage. IRSAD = Index of Relative Socio-Economic Advantage/Disadvantage. *Denominators may vary due to missing data. †Odds ratios, 95% confidence intervals and P values with logistic regression using generalised estimating equations with robust standard errors. ‡Participants were classified into deciles on the IRSD and IRSAD, based on their general practitioner’s geographic location. IRSD measures relative disadvantage so a high score implies a relative lack of disadvantage. §IRSAD provides a continuum score (or decile) of advantage (high values) to disadvantage (low values). Includes home duties, unpaid work and maternity leave.
