 * Publication bias: A judgment made on the basis of the question whether all the research evidence has been taken to account.

add citations:


 * "Trial design considerations: High-quality studies have clearly defined eligibility criteria and have minimal missing data.
 * Generalizability considerations: Studies may only be applicable to narrowly defined patient populations and may not be generalizable to other clinical contexts.
 * Follow-up: Sufficient time for defined outcomes to occur can influence the prospective study outcomes and the statistical power of a study to detect differences between a treatment and control arm.
 * Power: A mathematical calculation can determine whether the number of patients is sufficient to detect a difference between treatment arms. A negative study may reflect a lack of benefit, or simply a lack of sufficient quantities of patients to detect a difference."
