The Clinicians Speak, page-16

So the thing is, I can kind of understand what you're saying if you're looking at surgical case reports as a layman, and if you don't understand the medical field.

You look at each case and go "so what, 94% total body surface area burns, what difference did BTM really make. Besides, it's an N of 1".

Luckily you aren't the target market for the product.

Surgeons read these reports and understand the nuances. They understand how big of an issue infection is to graft failure, how difficult it is to keep a patient alive while awaiting definitive coverage of these wounds.

They know how rare it is for someone with burns such as that to survive. They know what typical results look like and can see the difference BTM makes.

This is how a new product/technique enters the field. Case reports, word of mouth, direct sales with reps present in theatres (at least for complex equipment such as orthopaedics devices, BTM is so simple this may not be required).

So while you may have a bit of an understanding of levels of evidence, you don't understand the industry.
