Does the peer review model affect the quality of peer review?

BioMed Central editors looked into the quality of reviewer reports and investigated several different factors that may influence it. The study published in BMJ Open shows that the quality of peer review is slightly higher in BMC Infectious Diseases that operates open peer review compared to BMC Microbiology operating single-blind peer review. Author-suggested reviewers provide reports of comparable quality to reviewers suggested by other parties, but are more likely to recommend acceptance of the manuscript.
