The letter “T” in abbreviations “T0, T1, etc.” stands for “threshold” applied to FPE values (see Table 2). We list the minimal (Min), maximal (Max), median and mean (together with the respective standard deviation—SD) numbers of articles associated with genes in the year when they crossed certain literature thresholds. As a trend, the number of actual articles is 2–3 times larger than the FPE value itself

Table 3 (A) shows the results for the E.coli literature whereas, (B) presents the data for the body of literature about human genes. Regardless of the taxon, we see similar trends with regard to number of actual publications for a given FPE range
