Format

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

Treatment Calcium or Placebo
Decrease Beginning-ending blood pressure

Details

The purpose of this study was to see whether daily calcium supplements can lower blood pressure. The subjects were 21 men; each was randomly assigned either to a treatment group or to a control group. Those in the treatment group took a daily pill containing calcium. Those in the control group took a daily pill with no active ingredients. Each subject's blood pressure was measured at the beginning of the 12-week study, and again at the end. The decrease in blood pressure (begin-end) was recorded (so a negative value means blood pressure increased).
