I do agree with and if there were unlimited resources would like to run all the tests I could since its better to be safe than sorry. In our scenario that was not the case, so I think even though coating A gave better results earlier on both coatings got the job done. So without being able to run all the tests we would like, none of the rats died with coating B so that would be the better option. Someone mentioned before that the stress that killed the rats could have been exacerbated from the coating. I do think that should be studied more to further rule out A or see if it was random. As for more coatings, I am assuming that enough research was done to conclude that A or B were the better options to go onto the implant. I believe in class we also mentioned that there would be further testing possibly on dogs and that the plan B would be to go back and do more work with coating A.
