NIH says larger grants have diminishing citation impact

An analysis by the National Institutes of Health has found that bigger grants don’t correspond to higher-impact journal articles.

The latest evaluation of what the NIH gets for its grant dollars was based on an impact metric developed by agency staff called the relative citation ratio. NIH’s head of extramural research Michael Lauer has used the relative citation ratio to judge the impact not just of individual papers but of the grants that pay for them.

According to his analysis, grants with more money over longer periods don’t deliver proportionately higher citation values.
