Figure 2. Grants stratified on the basis of publication and citation productivity for different percentile scores.
Graphs showing, for percentile scores of 20 or better, the number of grants in the top half (left bar) and bottom half (right right) of grants on the basis of publications (A) and citations (B). Grants in the top half on the basis of publication productivity (A) had ≥ 6 publications: mean percentile score of top half 9.244 ± 5.583, median 9; mean percentile score of bottom half 9.947 ± 5.612, median 10. Grants in the top half on the basis of citation productivity (B) had ≥ 128 citations: mean percentile score of top half 9.242 ± 5.625, median 9; mean percentile score of bottom half 9.939 ± 5.571, median 10. Fewer grants received a percentile score of zero as a result of rounding to the nearest whole number, as well as a change in the NIH percentiling algorithm since 2009.
