Sir, As far as I could make out, in response to the Learning Curve article on the importance of inadequately measured, unmeasured, and unknown confounds, Verma makes four broad points: (1) that the study of Coburn et al. [3] was methodologically adequate; (2) that my criticism of the study was unjustified; (3) that the authors did not intend to imply a cause–effect relationship between antenatal depression and infant health; and (4) that my article did not cite references to support the arguments for the existence of potential confounds.
