Interferon gamma production and tea drinking

Format

A data frame with 21 observations on the following 2 variables.

• InterferonGamma Measure of interferon gamma production

• Drink Type of drink: Coffee or Tea

Details

Eleven healthy non-tea-drinking individuals were asked to drink five or six cups of tea a day, while ten healthy non-tea and non-coffee-drinkers were asked to drink the same amount of coffee, which has caffeine but not the L-theanine that is in tea. The groups were randomly assigned. After two weeks, blood samples were exposed to an antigen and production of interferon gamma was measured.
