Fig. 1 Variations in fractionation regimen and median age by fractionation type by facility of treatment. Lighter shade: standard fractionation. Darker shade: hypofractionation use.

Fig. 2 (A) Increase in uptake of hypofractionation in New South Wales over time (though not reflected in all facilities). (B) Association of increasing age with increasing use of hypofractionation in all facilities but with marked variation in baseline rates. (C, D) Increase in hypofractionation over time, showing relatively more increase in the right breast, as expected to be evident primarily in facilities with a lower use of hypofractionation.
