All participants in the Internet arm had an opportunity to request an emailed Portable Document Format (PDF) version. Results: The Internet arm demonstrated a lower response rate (99/221, 45%) than the mail questionnaire arm (128/221, 58%) (absolute difference 13%, 95% confidence interval 4%-22%, P<0.01). Conclusions: Our Internet-based survey to surgeons resulted in a significantly lower response rate than a traditional mailed survey. Researchers should not assume that the widespread availability and potential ease of Internet-based surveys will translate into higher response rates. %M 15631963 %R 10.2196/jmir.6.4.e39 %U //www.mybigtv.com/2004/3/e39/ %U https://doi.org/10.2196/jmir.6.4.e39 %U http://www.ncbi.nlm.nih.gov/pubmed/15631963
