Quality
Impact Factor
The median Impact Factor (IF) of 2023 was 5.15 for total publications and 5.00 for original research articles. As for manuscripts published in key journals, i.e., journals with an IF ≥ 5, 50% of the total articles were published in key journals (Table 1).

| Median IF | 5.15 |
| % Key journals (IF ≥ 5) | 50% |
In 2023, the Research Sector produced manuscripts that were published in esteemed journals, such as Nature Medicine (IF, 82.9), Nature (IF, 64.8), and Circulation (IF, 37.8; Table 2).

Quartiles
In addition to the IF, rankings of journals in each subject category are divided into quartiles, which rank the journals from highest to lowest based on their IF. There are four quartiles: Q1, Q2, Q3 and Q4, which are explained in Table 3 below.
Table 3. Definition of quartile ranking of DDI publications
| Quartile | Definition |
|---|---|
| Quartile 1 (Q1) | Denotes the top 25% of the IF distribution |
| Quartile 2 (Q2) | Denotes middle-high position distribution (top 50% to top 25%) |
| Quartile 3 (Q3) | Denotes middle-low position distribution (top 75% to top 50%) |
| Quartile 4 (Q4) | Denotes lowest position (bottom 25% of the IF distribution) |
| N/A | No available score for the journal, not listed |
In 2023, a higher percentage of publications from the Research Sector were published in Q1 journals (76% of % indexed), while 94% of articles were published in either Q1 or Q2 journals; the breakdown of publications in quartiles Q1 and Q1 + Q2 is shown in Figure 2.
