ELI5: Explain Like I'm 5

Benefit risk

Imagine you want to go outside and play on a warm sunny day, but your mom is worried that you might get too hot and sunburnt. So she has to weigh the benefits of going outside and having fun versus the risks of getting too hot and sunburnt.

In the same way, when doctors prescribe medicine or suggest medical treatments, they have to consider the same thing. They have to weigh the benefits of a medicine or treatment, which means how it will help you feel better or improve your health, against the risks or potential harm it could cause you.

For example, if you have a headache, your mom might suggest you take some medicine to feel better. If you take too much medicine, it could make you feel sick or have other side effects, which is a risk. But, the benefit of the medicine is that it will make your headache go away, so your mom decides it’s worth the risk.

In the same way, doctors have to carefully consider which medicine or treatment will have the most benefits and the least risk for their patients. They do this by collecting data and carefully analyzing it to see how safe and effective a medicine or treatment is.

Ultimately, the goal is to find the best balance between benefiting the patient and avoiding any harm or risks. So just like your mom wants you to have fun outside but also wants you to stay safe, doctors want to help you feel better but also keep you safe and healthy.
