Further Analysis of Renewal Rates for New and Established NIGMS Investigator Projects: Additional Data Analysis-Figure 2

The following data are related to an NIGMS Feedback Loop post from June 18, 2015, on Further Analysis of Renewal Rates for New and Established NIGMS Investigator Projects.

Figure 2 Weighted Citation Counts per Million Dollars: No T2 Application, New Investigator: 211 projects, 23 weighted citations/$ million 25th percentile, 69 weighted citations/$ million median, 141 weighted citations/$ million 75th percentile; No T2 Application, Established Investigator: 343 projects, 13 weighted citations/$ million 25th percentile, 41 weighted citations/$ million median, 103 weighted citations/$ million 75th percentile; T2 Application, New Investigator: 543 projects, 51 weighted citations/$ million 25th percentile, 115 weighted citations/$ million median, 228 weighted citations/$ million 75th percentile; T2 Application, Established Investigator: 450 projects, 48 weighted citations/$ million 25th percentile, 112 weighted citations/$ million median, 220 weighted citations/$ million 75th percentile; T2 Not Funded, New Investigator: 270 projects, 38 weighted citations/$ million 25th percentile, 75 weighted citations/$ million median, 165 weighted citations/$ million 75th percentile; T2 Not Funded, Established Investigator: 209 projects, 25 weighted citations/$ million 25th percentile, 69 weighted citations/$ million median, 142 weighted citations/$ million 75th percentile; T2 Funded, New Investigator: 273 projects, 76 weighted citations/$ million 25th percentile, 152 weighted citations/$ million median, 301 weighted citations/$ million 75th percentile; T2 Funded, Established Investigator: 241 projects, 73 weighted citations/$ million 25th percentile, 175 weighted citations/$ million median, 325 weighted citations/$ million 75th percentile.

Figure 2. Total weighted citation numbers through the end of calendar year 2014 for publications within 5 years following the fiscal year of the initial award per million dollars of total cost for new R01 projects from new and established investigators funded by NIGMS between Fiscal Years 2004-2007. Citation counts were retrieved from Scopus (Elsevier) Link to external Web site. Weighted citation counts were calculated as the sum of the weighted citations for all publications associated with each project. The weighting factor was determined as described in Figure 1. Weighting the citation counts for how many NIH research grants were acknowledged in each publication more strongly affected the results for established investigator projects than for new investigator projects.

Figure 2A: No T2 Application, New Investigator, 211 projects, unweighted citations/$Million, 38 25th percentile, 94 median, 195 75th percentile; No T2 Application, Established Investigator, 343 projects, unweighted citations/$Million, 25 25th percentile, 70 median, 186 75th percentile; T2 Application, New Investigator, 543 projects, unweighted citations/$Million, 71 25th percentile, 179 median, 325 75th percentile; T2 Application, Established Investigator 450 projects, unweighted citations/$Million, 75 25th percentile, 190 median, 370 75th percentile; T2 Not Funded, New Investigator 270 projects, unweighted citations/$Million, 51 25th percentile, 115 median, 255 75th percentile; T2 Not Funded, Established Investigator, 209 projects, unweighted citations/$Million, 41 25th percentile, 120 median, 220 75th percentile; T2 Funded, New Investigator, 273 projects, unweighted citations/$Million, 120 25th percentile, 215 median, 415 75th percentile; T2 Funded, Established Investigator, 241 projects, unweighted citations/$Million, 145 25th percentile, 270 median, 520 75th percentile.

While the distribution of unweighted citation numbers for those projects for which a renewal application was submitted was shifted toward higher median counts for established investigator projects versus new investigator projects (Figure 2A), the new investigator projects had higher unweighted and weighted median citation counts when considering all new R01 grants funded by NIGMS between Fiscal Years 2004-2007 (see Figure 2B).
