What types of data would scientists need to scientifically conclude that honey decreases the risk of coughing in all people?

Scientists would have to perform repeated studies showing that coughing decreased in people who ate honey compared to those who did not eat honey. Scientists would need to conduct research with both kids and adults. Researching people from different age groups will help scientists prove that honey worked for most people. They would also need to determine if any other factors cause the coughing to decrease, such as the body’s natural defenses against the disease or even a change in atmospheric conditions.
