Dopamine Activity
Description
Twenty-five patients with schizophrenia were classified as psychotic or nonpsychotic after being treated with an antipsychotic drug. Samples of cerebral fluid were taken from each patient and assayed for dopamine b-hydroxylase (DBH) activity. The dopamine measurements for the two groups are in nmol/(ml)(h)/(mg) of protein.
Format
A data frame with 15 observations on the following 2 variables:
- nonpsychotic
dopamine activity level for patients classified nonpsychotic
- psychotic
