Question for the scientific reviewers: when reviewing a paper, which is pre-registered, do you compare contents pre vs actual submission? Does it or should it even matter in your judgement?

We validated some of the tests in the PerZeption battery, here color detection and discrimination tests.
Our PerZeption app’s tablet-based CVD screening got a spotlight in JOSAA! AIM & FInD methods showed strong results for efficient, accurate testing. Read more about how we’re advancing vision diagnostics in our latest blog perzeption.vision/Blog #VisionScience #ColorVision
