[Influence of impact factor on reporting sample size calculations in publications on studies exemplified by AMD treatment : Cross-sectional investigation on the presence of sample size calculations in publications of RCTs on AMD treatment in journals with low and high impact factors].

CONCLUSION: Publications in journals with higher IF more frequently reported a sample size calculation. More than 50% of the publications did not report any sample size calculation. Authors and reviewers of publications should pay more attention to the explicit reporting of sample size calculations. PMID: 31201561 [PubMed - as supplied by publisher]
