This dataset comes from a study of 184 patients with severe erosive esophagitis were allocated to one of two treatments. Costs and efficacy of the drugs were recorded. Questions from this study refer to differences in cost of the two treatments. A text file version of the data is found in the relation link.

This dataset comes from a study of female rats allocated to 1 of 4 doses of a drug, and then impregnated by similarly treated males. The pups were tested for developmental signs. Questions from this study refer to the relationship between pup response and dosage. A text file version of the data is found in the relation link.

This dataset comes from a study of 16 healthy males allocated to 1 of 2 treatment sequences: wafer/tablet or vice versa. Blood samples were taken and plasma levels were recorded. Questions from this study refer to whether the wafer treatment and the tablet treatment are equivalent. A text file version of the data is found in the relation link.

This dataset comes from a study of 24 healthy subjects allocated to 1 of 4 doses of a drug. Blood samples were taken and plasma levels were recorded. Questions from this study refer to the relationship between plasma level and dose. A text file version of the data is found in the relation link.

This dataset comes from a study of 14 healthy subjects given one dose of a drug for seven days. Blood samples were taken before and after treatment, and plasma levels were recorded. Questions from this study refer to the increase in plasma level after treatment. A text file version of the data is found in the relation link.

This dataset comes from two studies, one of 16 healthy young subjects and another of 14 healthy elderly subjects, each given a drug in two treatment periods. Blood samples were taken, and plasma levels were recorded. Questions from this study refer to whether age or gender affects plasma level.

This dataset comes from a study on 200 rats (100 of each gender) which were given one of 5 treatments, and then allowed to mate. At delivery, information on the pups was collected, and a sample of 8 pups (4 of each gender) was chosen from each litter. Body weights for these pups were recorded once a week for three weeks. Questions this study focused on refer to the safety of the treatments. A text file version of the data is found in the relation link.
