The close follow-up of the population by the nursing staff of the homes, the frequent rounds by the doctors, and periodic visits by the study coordinator may explain the apparently high incidence of pneumonia in our study; however, the incidence is within the rate (33 to 114 cases per 1000 population per year) previously reported in nursing home residents.
Use of imported khat may explain the apparently higher incidence of fascioliasis in this ethnic group residing in the United Kingdom.
Other prevailing diseases in Africa could provide another hypothesis to explain the apparently low incidence of dengue.
Worldwide studies have also demonstrated an apparently increased incidence of metastatic tumors [ 33], but this increase was less prominent in our series.
It is, therefore, likely that the apparently lower incidence of AKI in the developing world is the result of gross under-reporting [ 1, 10, 11].
Infection control measures subsequently introduced at this hospital apparently reduced incidence of CDI by more than 50% over 5 years [ 67].
New cases are still diagnosed due to the long latency of the disease, but apparently, the incidence peak has been reached in 2000 2005 for men [ 5].
Adjustments for socioeconomic factors accounted for the apparently low incidence of stomach and lung cancer and, to a lesser extent, skin cancer, which remained of borderline statistical significance.
The apparently low incidence of independent venom gland evolution in catfishes stands in stark contrast to the results obtained for venomous spiny-rayed fishes, in which venom glands appear to have evolved independently no fewer than nine times [ 18].
In addition, both general increased survival in the population and improved treatment of people with MS might account for the increase in MS prevalence despite an apparently stabilizing incidence.
