Table 1.

Perceived advantages and disadvantages of peer review blinding models (3,15,16).

Blinding	Potential advantage	Potential disadvantage
Open review	More objective review with constructive and thoughtful advice; more responsible engagement by the reviewer; transparency	Reviewers unwilling to review without anonymity; reviewers avoid giving honest critical feedback, especially young reviewers who do not wish to displease “authority”
Single-blind review	Reviewers, especially young ones, can provide critical feedback without worrying about authors negative reactions or other consequences	Reviewers can be aggressive or impolite while hiding behind the shield of anonymity; they can deliberately drag out the review process for personal gain or engage in other types of scientific misconduct
Double-blind review	Prevents reviewers from bias due to the authors’ origins, faith or previous work especially if the authors are famous and influential in the field.	Perfect double blinding is rarely possible
