According to the study among 5000gluten sensitive person 2000 were diagnosed with migrsbe therefore the rate will be
2000×100÷5000=40% risk with gluten sensitivity
In 8000 non gluten sensitivity person 1600 were diagnosed migraine
1600×100÷8000=20% risk with non gluten sensitivity
The relative risk will be 1:2 for gluten sensitivity and migrane
