US Health Expenditure vs US Life Expectancy

US Health Expenditure and US Life Expectancy correlate at r = +0.41 over 24 years (2000–2023), p = 0.046. With the time trend removed, r = +0.19. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 0.046) and the association survives trend removal (detrended r = 0.19). Correlation still isn't causation, but this one isn't an obvious artifact.
