Surprising Findings

The dose-response relationship — higher caffeine intake showed stronger protective effects — was clearly demonstrated in subgroup analysis.

Many assume only moderate intake is beneficial; this suggests even higher consumption (up to 300+ mg/day) may offer greater protection, which contradicts common warnings about caffeine overuse.
