Model-based estimates of condition prevalence generated using mixed effects probit regression. Prevalence estimates are expressed as proportions. N = 9436 people in residential aged care during 2014–2017 from 68 facilities in NSW and ACT. Case estimates were generated by multiplying the age- and sex-specific prevalence estimates by the age and sex distribution of the Australian residential aged care population in 2017 based on GEN aged care data published by the Australian Institute of Health and Welfare. F estimates for females, M estimates for males, PUD/GORD peptic ulcer disease/gastro-oesophageal reflux disease. Detailed information on the specific conditions and criteria used in the condition categories presented in this table can be found in Supplemental Table 1
