Discussion
The authors cite articles that refer to several other studies, many with contradictory findings. However, the authors did a good job of trying to hypothesize why the findings were contradictory. This article is another step in addressing the topic posed, but it did not necessarily answer the questions it raised. However, rarely, if ever, does one study offer sound results that solve the problem posed. In the future, more studies should be done using similar methods but with larger sample sizes that are more heterogeneous to get a better representation of the population.
