"Is explaining QALYs going to turn people off?"

QALYs are a major component of this talk. You could make another talk without QALYs, but a lot of pieces of this one, like demonstrating the huge range of effectiveness in health interventions, depend on them.

"The presentation could be more engaging - less on each slide, more colorful"

I didn't get the sense that people in the room were tuning out or would have paid more attention with flashier slides. But this probably varies based on where you are.

"Thank you for transcribing this!"

I actually only cleaned up the transcription. The initial transcription was made by someone else because one of the people who wanted to watch the talk is deaf.
