The hypothesis of this study was that the use of a more sensitive imaging modality (ultrasound) would lead to a different (most likely higher) prevalence estimate for OA at the dominant hand, knees and hips when compared to previous radiographic studies.
For both study populations, prevalence rates were based on administrative data for one 12-month period and most likely underestimated actual prevalence rates.
Thus, the observed prevalence rates most likely overestimate the real prevalence within the entire population aged 65 years and older.
Thus, the trials included in the review most likely underrepresent the prevalence of men with prostate cancer and depression.
The higher frequency of antihistamine drugs most likely reflects higher prevalence of allergies and/or cold symptoms in the CFS population.
Although this would be most likely to bias prevalence estimates rather than the associations between disorders and other factors, it has meant that those with high levels of psychopathology at baseline were less likely to participate in the study.
In general, protocols for empirical antimicrobial treatment are based on information about the most likely pathogens involved, prevalence of resistance in these pathogens and risks of unfavourable outcome when therapy is not appropriate.
In study A, 45.1% of the expected CVM affected calves was found, while only 23.0% was obtained in study B. As the inherited basis for CVM has been determined [ 3], it is most likely, that the prevalence of affected calves was reduced due to a high rate of intrauterine mortality.
Because we are most likely dealing with prevalences below 50% (and those above 50% are all treated the same according to the WHO recommendations), we decided to proceed with the pool size of four.
This being a point prevalence cross-section study, the total skin disease burden is most likely underestimated since point prevalence studies often miss diseases of short duration.
