MR uses genetic variants as "natural experiments" to determine if an exposure (like high blood pressure) truly causes a disease (like stroke), rather than just being associated with it. вљ–пёЏ The Three Pillars of MR Validity
For an MR report to be considered valid, it must demonstrate that the genetic instruments (SNPs) meet these criteria: Diseases - Mr Validity

: Exposure and outcome are measured in the same group of people.
: Used to study the causal impact of alcohol, smoking, blood pressure, and cholesterol on various chronic diseases . вљ пёЏ Challenges to Validity
: There are no common causes (confounders) shared between the genetic variants and the outcome.
