The qualitative and quantitative research methods complimented each other by allowing results to emerge from the heritage science community and related disciplines, while at the same time the prevalence and structure of attitudes in the community could be assessed in a statistically robust and reliable way.
Human rhinoviruses (HRVs) are the most frequently detected pathogens in acute respiratory tract infections (ARTIs) and yet little is known about the prevalence, recurrence, structure and clinical impact of individual members.
Even in the study on the prevalence and structure of psychopathic traits using a very large world sample (N = 33,016), Europe was represented only by German and Austrian populations, i.e. typical West European nations [ 22].
We aimed to explore and compare the prevalence and factor structure of psychotic symptoms in chronic ketamine and methamphetamine users.
There were no differences in chronic pain prevalence by family structure.
Even after accounting for differences in age structure, prevalence is lower in Africa than in Europe and Asia (48, 49).
However, a systematic and comprehensive assessment of the prevalence, distribution, and structure of these retroelements has been lacking.
Because random shearing of the full-length target molecule is used in some protocols, we have also modeled the effects of shearing to an average length on the prevalence of secondary structure in selected targets.
However, there are significant differences in cancer burden across the world and they are mainly attributed to the variation in the age structure; prevalence of risk factors such as nutrition and diet, infection and tobacco; environmental and occupational factors; availability and use of cancer screening services; and access to and quality of the cancer treatment [ 4, 9, 24– 26].
The inconsistency in the results observed between the provinces could be attributable to a variety of factors not assessed in this analysis: differential patient and tracer subdistrict sample sizes between provinces, variability in reporting and recording of TB treatment outcomes, as well as differences in TB burden, HIV prevalence, infrastructure, socioeconomic structure and geography.
