Exemplar countries across SDI quintiles showing favorable (A) and unfavorable (B) age-period-cohort effects. Age distribution of deaths from 1992 to 2021 shows the relative proportion of breast cancer deaths across 16 age groups (15–19 to 90–94 years). Local drifts show the fitted longitudinal age curves of breast cancer mortality (per 100 000 person-years) across 16 five-year age groups (15–19 to 90–94 years) and the corresponding 95% CIs. Age effects show the fitted longitudinal age curves of breast cancer mortality (per 100 000 person-years) and the corresponding 95% CIs. Period effects show the relative risk of mortality of each period compared with the reference (period 2002–2006) adjusted for age and nonlinear cohort effects and the corresponding 95% CI. Cohort effects show the relative risk of mortality of each cohort compared with the reference (cohort 1948–1956) adjusted for age and nonlinear period effects and the corresponding 95% CI. SDI, socio-demographic index; CI, confidence interval
