Interferon gamma production and tea drinking
A data frame with 21 observations on the following 2 variables.
InterferonGammaMeasure of interferon gamma production
DrinkType of drink:
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.
