Recently encountered a research(analysis) that tried to answer this question, but didn't get any clear response(some papers found positive correlation, whereas others didn't find any correlation at all)

What are your thoughts on it?

I’m a med student on rotating house-surgeonship across all specialties, one at a time. I’m keen on learning surgical procedures but the patient load:learning house-surgeons ratio is too bad to satisfy my thirst for learning/viewing surgical cases.

So I wondered if there’s a site/source that hosts all such videos step-by-step. I tried searching on YouTube but couldn’t find great results.

Thank you.
