Results are presented as incidence rate ratios, RR (the effect size of the interaction terms are exponentiated).
The parameter estimates are the interaction variable for CTC phase by age group, adjusted for age, sex, socioeconomic index for area remoteness and year. Results statistically significant at p=0.05 are shown in bold font.
*Sports injury are excluded.
