You need someone who knows SA to identify the features of the data that need to be quantified (apnea duration, frequency, associated sleep phase, BP, etc.). when these variables are extracted from the data, statistical analyses can be performed by someone who is ignorant of SA, but knows her way around SAS or R or whatever. If / when a trend in a subgroup is identified the SA expert can look at the data and assess whether what is found is clinically meaningful.
With 2.5 years lead time, you'd want to hope that corx would have lined up the SA consultants to make sense of the data. There are plenty of statisticians who can handle the data analysis. The SA experts would not be responsible for the data mining itself, but rather would interpret the results of the statistical analysis.
If the dataset was complete by early/late September, there is just no way that they are still figuring out what it all means. Nobody is that incompetent when the company's livelihood is riding on it.
