the following two questions: 1) A study was done with randomly assigned infant mice to be given antibiotics or not. After the mice were adults, their weights were recorded and rated in a way that classified them as obese or not. The conclusion of the study was that the mice given antibiotics were more likely to be obese as adults. Can this study be used as evidence of causality? Yes No 2) A study was done with humans where it was found that children who were given antibiotics before they were one year old (for example, for ear infections) were more likely to be obese as adults than children who were not given antibiotics before they were one year old. Can this study be used as evidence of causality? Yes No
