The article introduces a new method for figuring out cause and effect in studies when some important factors are not measured. This method uses information from multiple outcomes to tackle this issue. The key idea is that these outcomes are connected in a specific way. By looking at at least three outcomes together, the method can figure out the cause and effect relationships. The researchers also provide tools to estimate these relationships in a specific type of model. They tested their method on both made-up and real data to show that it works well.
