The text describes the mean severity of day heartburn for evaluable patients by study day. The severity is rated on a scale from 0 to 3, where 3 indicates a severe heartburn and 0 indicates no heartburn. The study compares the effectiveness of a placebo with two different doses of Lansoprazole, a drug used to treat acid reflux. The data is presented graphically over a period of 25 days from the start of the treatment.*
