Does it keep p-values and figures exact?

Yes. Numbers are kept as written, and slides never add results the paper doesn't report.

Can I add my own framing?

Yes. Say who it's for, like a lab meeting or a 10-minute talk, and the deck follows it.

Yes. Every slide gets notes you can read in presenter view or in PowerPoint.

Abstract

We tested whether a 20-minute nap improves recall in 96 undergraduates, split into nap and wake groups of 48.

The nap group recalled 31% more word pairs than the wake group (p < 0.01). The effect held at a one-week follow-up.
