Procedure: 1 Review the summary of a published scientific study below: Patients with multiple sclerosis frequently suffer from blurred vision. Drug X was developed to reduce blurred vision in healthy patients, but the effectiveness had not been tested on those suffering from multiple sclerosis. A study was conducted to determine if Drug X is effective at reducing blurry vision in multiple sclerosis patients. To be considered effective, a drug must reduce blurred vision by more than 30% in patients. Researchers predicted that a 20 mg dose of the drug would be effective for treating blurred vision in multiple sclerosis patients by reducing blurred vision by more than 30%. Drug X was administered to groups of multiple sclerosis patients at three doses (10 mg/day, 20 mg/day, 30 mg/day) for three weeks. A fourth group of natients was given a placebo containing no drug X for the same length of time. Vision clarity was measured for each patient before and afte, che three-week period using a standard vision test. The results were analyzed and graphed (See Figure 2), illustrating that more patients receiving 20 mg/day of Drug X per day exhibited a higher reduction in blurred vision than did the other groups. Researchers concluded that a 20 mg dosage of Drug X was effective for treating blurred vision in patients with multiple sclerosis. The researchers then submitted their work to a medical journal where it was reviewed by a panel of vision and multiple sclerosis experts before being published.
