Map of selected mine fire exposed SA2s in Victoria.
Superimposed dots are the location of schools in the impacted areas.

Illustration of Bayesian interrupted time series hierarchical meta-regression.
*Means and SE of test results each year for individual students’ grade level at each school. The subgraph (A) represents a theoretic model of the mine fire interruption effect.

School profile (in the year 2014) and NAPLAN participation rate by exposure area.
Fig 3.
Box plot of school mean NAPLAN score for pre-mine fire period and post-mine fire period by exposure group for each domain and grade level.
Fig 4.
Trends of predicted centred NAPLAN scores (predicted margins when all covariates are fixed at reference values) with error bars by exposure group for each academic domain.
Note: centred NAPLAN scores represent score differences of schools compared with the regional Victorian average scores in the matching year, grade level and domain; the grey line indicates the time of the mine fire.
