An additional year of secondary school was associated with a 0.88% reduction in dementia incidence over 50 years, according to a study funded by the US National Institutes of Health.[^1]

The research analysed medical records for more than 100,000 UK Biobank participants, tracking outcomes following a 1972 national reform that raised the school leaving age from 15 to 16.[^2]

Five-year survival for United States paediatric cancer patients increased from 60% in 1975 to 88% in 2017, per findings published in the Journal of the National Cancer Institute.[^3]

That same dataset recorded a persistent survival gap by race. Non-Hispanic Black patients had an 80.8% five-year survival rate in 2017, compared to 88% for non-Hispanic white patients.[^4]

This suggests the large observed gains in paediatric cancer outcomes have not been distributed evenly across patient groups.
