Table 1.
Total published items, total citations and Hirsch h-index for researchers with different patterns of publishing presence in the scientific literature, 1996–2011.
Table 2.
Number of published items indexed in Scopus in each calendar year and proportion published by authors with uninterrupted, continuous presence (UCP) from 1996–2011.
Figure 1.
Median citation metrics for authors in the 4 groups according to the total number of papers they authored in 1996–2011: (A) total citation count, (B) h-index, (C) total citation count, limited to Medical Research scientists, (D) h-index, limited to Medical Research scientists.
For each of the 4 groups, data are presented for bins of authors spanning 10 papers in the total count of papers (0–10, 11–20, 21–30, 31–40, 41, 50, 51–60, etc), provided that there are at least 50 authors in the bin.
