3 - information about the sample:

. method;

. size;

. inclusion/exclusion criteria,

. attrition/loss to follow up/response rate, if any;

important characteristics of the sample.

Appraise and debate the sampling methods and determine the quality of the sampling procedures in reducing bias. Consider the following questions:

4. Was the sampling method and inclusion/exclusion criteria adequate to reduce sampling bias?

5- Are the sample characteristics representative of the target population?

6 - Was the sample size adequate?

7- 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?
