Rapid Response:

Very important albeit overlooked variables: age, central obesity, and acanthosis nigricans

The article is highly relevant in day-to-day clinical practice. The incidence of Type 2 DM is highly influenced by other important albeit overlooked variables: age (increase with increasing age, increase with increase in central obesity, particularly intra-abdominal fat, and increase with presence of acanthosis nigricans, the cutaneous manifestation of insulin resistance). I am sure c-statistic could have been much improved, if these easily and clinically measured variables could have been included in the analysis.

In future, analysis of these easily and clinically measured variables, could be considered with advantage.
