An investigator wanted to examine drinking green tea and the incidence and severity of flu in a prospective cohort study. The investigator recruited 1000 people and asked them about their tea consumptio Of the 1000, people 200 reported drinking tea regularly, 100 occasionally, and the remaining 700 reported never drinking green tea. After 3 months of follow up, the investigator collected on the flu incidence and severity in the following table. Calculate The Risk Ratio (RR) for flu among regularly drinking green tea vs. never :______ The Risk Ratio (RR) for severity of flu among regularly drinking green tea vs. never : The interpretation of this finding is: Green Tea Drinking Regularly drink green tea Occasionally drink green tea Never drink green tea Developed flu 30 13 100 Did not develop flu 170 OF.
