Would have to search to find the exact studies, but it's been found that a hamburger menu will lower engagement and result in shorter user sessions (particularly, the user will visit less pages). The intuitive answer as to why is that you're burying a very important navigation menu by making it an extra click away (and hidden from view by default). Anecdotal side note, but when I was working on a startup in some industry, we found that our largest competitor by an order of magnitude had a navigation bar at the bottom in their mobile app, while everyone else in the space used the hamburger menu. The experience made it seem like this is common knowledge at the higher levels of app design. Even Apple has come out and explicitly spoken against the hamburger menu as a design element for iOS apps, and instead recommends tab bars.
