I guess it is good that they are being transparent with the data, but it is largely useless at this point as it isn't normalized at all and is in a way self-reported. You obviously can't conclude that chicken is bad and goat is good, but you can't really conclude anything else either. One potential mechanism is the taurine levels but the set of DCM cases contain low, normal, and high levels of taurine at similar rates. I think they are doing a reasonably good job, though. There are a number of controlled (though small sample size) studies ongoing.
