As stated previously there is only one way to prove that one Rx is better than another, and that is a randomised control trial. All other studies will only point a researcher in the right direction.
No one is going to conduct an RCT into using nitrox over air, not even DAN, these trials cost millions, and what would DAN actually benefit out of it?? Not much!!! The reason that drug companies spend millions on trials is that they get billions back.
Doctors don't need to have empirical evidence to make recommendations, yes it's nice to have, but in the case of DCS it just isn't there. You will find some papers on the subject of air, nitrox, and trimix use, but you're not likely to find an RCT let alone systematic review with meta-analyses.
You seem to want to have published evidence of the benefit of using nitrox on an air table yet the research for air tables is theoretical only anyway. Why not look for a RCT/Systematic Review into the use of air on air table over just not using a table at all??? The evidence that led to the development and use of air tables would have been exactly the same as what led to the developement and use of nitrox tables - and subsequently the recommendation of using nitrox on air tables.
