Our analysis of genetic diversity of Chilean rainbow trout indicates that the contribution of trout escaping from fish farms is substantial, and the incidence of escapees is widespread.
This study shows that there is substantial variation in incidence of cancer of the gastrointestinal tract by social class in Finland.
[ 2] In Canada, where ovarian cancer accounts for 4% of all female cancers or 31%ofall genital cancers in women, it is estimated that in 2001 there were 2,500 new cases and 1,500 deaths.[ 3] There is substantial variation in incidence rates of ovarian cancer internationally, from 3/100,000 in central Africa to 13/100,000 in northern Europe.
Overall, our findings indicate that B. pertussis incidence is substantial in adults aged ≥50 years that considerably exceeds the generally reported disease incidence.
There is substantial variation in the incidence of T1DM and T2DM across the major racial/ethnic groups in the U.S. The incidence of T1DM is highest among non-Hispanic whites (NHWs) and lowest in American Indians (3).
The difference in the incidence is substantial for HL, NHL and MM (2·5- to 5-fold), whereas the leukaemias (AML, ALL and CML) have a more similar incidence.
In Canada, there is substantial variation in CRC incidence and mortality rates among provinces [ 2].
There is substantial international variation in incidence rates but these tumours are most prevalent in North America, Europe, and other areas of the world with similar lifestyles and dietary habits.
There is substantial clinical evidence that the incidence of depression and mortality after acute coronary events are strongly related.
Although there is substantial variation in the standardized incidence ratio of different cancers posttransplantation, the greatest prevalence is seen in cutaneous squamous cell carcinoma (cSCC) (7)–(9).
