 I need the following for this article.

1. Appraise and debate the sampling methods. Consider the following questions:
   • Was the sampling method and inclusion/exclusion criteria adequate to reduce sampling bias?
   • Do the sample characteristics representative of the target population?
   • Was the sample size adequate?
   • Was there a decrease in sample size?  If so, did the researchers identify decreases early and attempt to reduce the impact?  Was a decrease, if any, adequately explained by the researchers?
   • How would you rate the quality of the sampling procedures and your confidence in drawing inferences to the target population?
