The present study takes a closer look at these citations and combines the presentation with a systematic review of methods and theoretical approaches in Internet addiction studies, published between January 2000 and July 2013.

Phenotypic Traits and Genetic Markers Associated with Smoking

We assessed any associations between these molecular markers and phenotypes of smokers.
