There's a case for adding some weighting by flight hours/km as the widebody flights are on average longer, but it's less clear what that should be, especially with most of the accident risk being takeoff or landing. On the other hand, the displayed safety record of the 747-400 is exceptionally good. Much of the widebody/narrowbody distinction is just statistical noise (as others have pointed out, a third of the 777 accidents are a single flight being hit by a missile, and another third a suspected suicide) and widebodies are less common aircraft so the accident rates are noisier. ATRs are turboprops that fly a lot into relatively difficult-to-land small airports. Also, the accident rate under-counts the amount of flights they've actually made by more than some of the other aircraft.
