Figure 1. NIDDK Extramural Research Funding by Mechanisms (excluding Special Statutory Type 1 Diabetes Program) From FY2014 to FY2023
This is a horizontal bar chart whose x-axis displays percentages from zero to one hundred in increments of twenty percentage points. The y-axis shows fiscal years ascending from the bottom, starting with 2014 and ending with 2023 in increments of one year. Each horizontal bar corresponds to a fiscal year and is split into the following categories in order from left to right: Research Project Grants (RPGs), Small Business Innovation Research/Small Business Technology Transfer (SBIR/STTR), Research Centers, Research Careers, Other Research, Training, and Contracts/Interagency Agreement (IAA). In general, most categories represent the same proportion of the budget from year to year. The RPG budget is over seventy percent of the NIDDK extramural budget.
Figure 2: NIDDK Research Project Grants Funding by Activity Codes (Competing and Non-Competing, excluding Special Statutory Type 1 Diabetes Program) from FY2014 to FY2023
This is a horizontal bar chart whose x-axis displays percentages from zero to one hundred in increments of twenty percentage points. The y-axis shows fiscal years ascending from the bottom, starting with 2014 and ending with 2023 in increments of one year. Each horizontal bar corresponds to a fiscal year and is split into the following categories in order from left to right: R01, R21, R37, P01, U01, Other R (includes DP), and Other U. Starting in 2016, the R01 awards represent a larger proportion of RPG awards, increasing from 70 percent in 2015 to 84 percent in 2023. During these same years the fraction of R37, P01, and U01 awards decreased somewhat, with U01s showing more significant fluctuations going from 17% in 2015 to 8.2% in 2023.
Table 1: NIDDK Investigator-Initiated R01 Paylines
Table 1 details the NIDDK payline thresholds by fiscal year. The columns from left to right are the fiscal year, general payline, grants over $500,000 in direct costs payline, the new investigator payline, the Early Stage Investigator (ESI) payline, and the ESI first competitive grant renewal payline. The rows from top to bottom are the Fiscal Years from 2011 to 2023 and contain the payline values for the columns described.
Figure 3A: Number of NIDDK Investigator-Initiated (excluding ESI) R01 Applications and Competing Awards in FY2023 By Percentile Score
This is a stacked bar chart whose x-axis is percentiles from one to fifty in increments of one. The y-axis is the number of applications or awards from zero to fifty in increments of five. Each bar shows the total number of applications and awards that were scored at that percentile. For some bars, there are two colored areas, one showing the number of unfunded applications, in orange, and one showing the number of awards, in blue, at that percentile. These data demonstrate that nearly all applications that scored at or below the payline (the sixteenth percentile) received funding in fiscal year 2023. The fraction of applications that are funded tapers off at increasing percentiles, with no applications funded at a percentile of forty-three or higher.
Figure 3B: Number of NIDDK Early Stage Investigator (ESI)-Initiated R01 Applications and Competing Awards in FY2023 By Percentile Score
This is a stacked bar chart whose x-axis is percentiles from one to fifty in increments of one. The y-axis is the number of applications or awards from zero to sixteen in increments of two. Each bar shows the total number of applications and awards that were scored at that percentile. For some bars, there are two colored areas, one showing the number of unfunded ESI applications, in orange, and one showing the number of awards, in blue, at that percentile. These data demonstrate that nearly all applications that scored at or below the payline (the twenty-fifth percentile) received funding in fiscal year 2023. The fraction of applications that are funded tapers off at increasing percentiles, with no applications funded at a percentile of thirty-six or higher.
Figure 4: Number of Competing NIDDK R01 Applications Received for Funding from FY2014-FY2023
This is a stacked bar chart whose x-axis shows fiscal years between 2014 and 2023 in increments of one year. The y-axis shows the number of competing R01 applications received; it ranges from zero to three thousand five hundred in increments of five hundred. For each fiscal year, the height of the bar represents the total number of competing R01 applications received by NIDDK, and the bar is subdivided to indicate the portion of applications that are new, in blue, and the portion that are renewals, in orange. The data table below the graph provides the actual values for each group across the fiscal years.
Figure 5: Total Number of NIDDK R01 Awards from FY2014-FY2023

This is a line chart whose x-axis shows fiscal years between 2014 and 2023 in increments of one year. The y-axis shows total awarded dollars from six hundred million dollars to thirteen hundred million dollars in increments of one hundred million dollars. There are two lines on the chart and from top to bottom, using 2023 as the reference point, represent: 1) the actual total cost of R01 grants awarded (blue); and 2) the total cost of R01 grants awarded when adjusted for inflation using the Biomedical Research and Development Price Index (BRDPI) (orange). Both lines on the chart starts slightly above seven hundred million dollars in 2014. The total cost of R01 awards rises steadily from 2014 to 2023 where it reaches just above twelve hundred million dollars. The BRDPI line has a lesser increase from 2014 to 2023 where it rises to just over nine hundred million dollars.

This is a stacked bar chart whose x-axis shows fiscal years between 2014 and 2023 in increments of one year. The y-axis displays the number of R01 awards from zero to three thousand in increments of five hundred. Each vertical bar represents the total project count for each fiscal year. Each bar is divided to show the R01 awards that have a single principal investigator (PI) (blue), and R01 awards that have multiple PIs (Multi-PI) (orange). In 2014 there were about two thousand R01 awards with approximately eleven percent of those awards having a multi-PI component. From 2014 to 2023, the number of R01 awards steadily increased and reached over two thousand four hundred awards. During the same time period, the number of multi-PI grants also increased steadily. The number above each bar represents the proportion of multi-PI R01 awards in each fiscal year.

The Success Rate represents the percentage of the funded PIs in relation to the PIs who submitted an application. For five of the cells within the table, data had to be redacted per NIH policy because the number of people counted was less than eleven. The values in these cases are represented as a double asterisk.
