  1. Bold text - significant coefficients (p < 0.05); italicised text - marginal coefficients (p < 0.08). Note differences in coefficient magnitudes for IR and DR interaction terms; subfield main effect reached significance in DR model, but not IR model. See Supplementary Tables 1 and 2 for IR and DR full model outputs, respectively.
