They've made a framework for combining datasets from different sources, something that is tricky in general because of the need to guard against unknown differences between experiments. It's also not obvious that there should be a statistical framework because combinations is usually something done carefully by people familiar with both experiments, so essentially it's on a case by case basis and not wholesale across the field.
