Outcomes
What capsaicin actually does, by outcome
Each row is one outcome with effect size, evidence base, the dose that worked in trials, and time to first effect. Magnitude tiers come from native-unit MCID where available, Cohen's d otherwise.
Brings down both systolic and diastolic, especially when baseline runs high.
