Unfortunately I find this a very limited study. There are several point of care tools that should have been consulted in addition to UpToDate if the authors wanted a comprehensive understanding of the clinical impact of medical journals in point of care tools.<br> Additionally there are several other methods for studying reach and possible impact of journal articles such as altmetrics. A more robust article featuring several point of care products that included different types of altmetrics, while not perfect, would have given a much better picture of clinical impact of medical journals compared to the traditional impact factor.
