How intrinsically valuable is a medical study to a layperson simply for being peer re

Does a study in a peer reviewed journal that's not published by a reputable scientist and has not yet been replicated have any value to the layperson? Basically, does a study in a peer reviewed scientific journal have any value simply by the virtue of being a peer reviewed study? People doing reviews can only spot errors in study design but they can't, for example, tell whether the data being submitted is false and the layperson is even further from being able to determine a study's reliability.

Is it all down to just reputation and replication?
