The authors respond:

We thank Dr. Chiolero1 for his interest in our commentary.2 We agree that observational data must be used with caution, and lots of data must be used with lots of caution. The concluding paragraph of the commentary echoes Dr. Chiolero’s point: we need to avoid the illusion that big data is a panacea for all the threats to the validity of observational studies.
