Anecdotal, but I've never heard of an apartment building fire where people get trampled trying to escape. This in Europe where many if not most countries do not mandate a second escape route for midrise buildings. It's simply not a problem. You're supposed to shelter in your apartment anyway, which almost always is much safer than the hallway in case of a fire.
Yes, but that is about large crowded events specifically, where the crowds can be tens to hundreds of times larger than the number of residents in a midrise, and remaining in a specifically constructed fire-and-smoke-resistant shelter (one’s home) is not an alternative.
