They were then asked to re-answer the original 14 questions. Results: We found no statistically significant differences in the rates of correct or incorrect answers using the PubMed main screen or PubMed Clinical Queries. The rate of correct answers increased from 50.0{\%} to 61.4{\%} (95{\%} CI 55.0{\%}-67.8{\%}) for the PubMed main screen searches and from 50.0{\%} to 59.1{\%} (95{\%} CI 52.6{\%}-65.6{\%}) for Clinical Queries searches. These net absolute increases of 11.4{\%} and 9.1{\%}, respectively, included previously correct answers changing to incorrect at a rate of 9.5{\%} (95{\%} CI 5.6{\%}-13.4{\%}) for PubMed main screen searches and 9.1{\%} (95{\%} CI 5.3{\%}-12.9{\%}) for Clinical Queries searches, combined with increases in the rate of being correct of 20.5{\%} (95{\%} CI 15.2{\%}-25.8{\%}) for PubMed main screen searches and 17.7{\%} (95{\%} CI 12.7{\%}-22.7{\%}) for Clinical Queries searches. Conclusions: PubMed can assist clinicians answering clinical questions with an approximately 10{\%} absolute rate of improvement in correct answers. This small increase includes more correct answers partially offset by a decrease in previously correct answers.
