For example, they could have shown that there was a difference at the 94% confidence level, which would have been "no statistical difference" because it's generally required to have a 95% confidence to show a statistical difference. That suggests that there is a difference, but it's small enough that it doesn't show up statistically unless you get a big enough sample.
