CI = confidence interval.
Poisson regression (spline function, adjusted for day type [working day or non‐working day/public holiday] and year; baseline period: 1 February – 16 March 2020).
For cancers common in both sexes (melanoma, colorectal cancer, lung, head and neck cancers, haematological malignancies).
Based on residential address, using the Google Geocoding API (https://developers.google.com/maps/documentation/geocoding/overview), spatially joined to Australian Bureau of Statistics Statistical Area 1 (SA1) polygons. 4 Area‐based socio‐economic quintiles were based on 2016 Australian Bureau of Statistics census data. 5
