Sunspot Number vs US Health Expenditure
Sunspot Number and US Health Expenditure correlate at r = -0.58 over 24 years (2000–2023), p = 0.0028. With the time trend removed, r = -0.57. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.0028) and the association survives trend removal (detrended r = -0.57). Correlation still isn't causation, but this one isn't an obvious artifact.
