This was not an experimental study, as the word "biobank" in the abstract should have made clear.
Biobanks are about collecting more detailed data on more individuals than would be possible for any particular study, and spending a lot of effort to ensure the quality and consistency of the data. Any conclusion you can make from biobank data is a hypothesis likely worth investigating. And publishing, because further studies would likely take years.
You would then collect new data designed to answer the specific question in your subsequent study. But due to financial constraints, that new data would likely be less detailed, smaller in scale, and of lower quality.
