Background/Objectives: To assess whether the type of peer-review (single-blinded vs double-blinded) has an impact on nationality representation in journals.
Methods:A cross-sectional study analyzing the top ten nationalities contributing to the number of articles across 16 ophthalmology journals.Results: There was no significant difference in the percentage of articles published from the journal's country of origin between the top single-blind journals and top double-blind journals (SB= 42.0%, DB = 26.6%, p=0.49) but there was a significant difference between the percentage of articles from the US (SB=48.0%, DB=22.8%, p=0.02). However, there was no significant difference for both country of origin (SB =38.0%, DB =26.6%, p=0.43) and articles from the US (SB=35.0%, DB=22.8%, p=0.21) when assessing the top 8 double-blind journals matched with single-blind journals of a similar impact factor.The countries that most commonly made the top ten lists for highest number of articles were the US (n=16, 100%) and England (n=16, 100%). This held true even for journals established outside the United States (US=11/12, England=11/12).
Conclusions:There was no statistically significant difference in country-of-origin representation between single-blind journals and double-blind journals. However, higher income countries contributed most often to the journals studied even among journals based outside the US.
