In Reply:

We would like to thank Dr Harrow (1) for pointing out a flawed example in our paper (2). As he notes, the recommended question should be:

How many cigarettes do you smoke per day?
[    ] None    [    ] 1–4    [    ] 5–24    [    ] 25 or more

The previously recommended category “4 or less” was a typographical error.

Sincerely,
