With 1,000 cases and 1,000 controls, overall analysis will have 90% power to detect OR ≥ 2 with exposure in controls ≥5%, whatever the prevalence of exposure associated with a case.
With 100 cases and 100 controls per site, analysis in a particular site will have 80% power to detect odds ratios (OR) ≥3 with prevalence of exposure ≥20% for the controls, whatever the prevalence of exposure associated with a case.
Whatever the prevalence of non-canonical miRNA-mediated regulation, a wide gulf separates the theoretical possibility of xenomiR effects at low copy numbers from the non-physiologic conditions of miRNA-target assays that are often used to establish canonical, direct regulatory effects.
International guidelines recommend that, whatever the HIV prevalence, a positive rapid test must be confirmed by EIA or at least one other rapid test [18].
Using an expensive treatment option, the routine use of the test remains cost-effective whatever the MRSA prevalence.
On the basis of these data and previous correlations, we demonstrate our conclusions: whatever the age, a prevalence of pigmentation disorders occurs, with significant differences between the two groups, and these signs are the most connected to photoaging.
By comparing evaluations of clinical signs between the two groups for each 10-year cluster, we demonstrated that whatever the age, a prevalence of pigmentation disorders for the sun-seeking group (ie, pigmentation) is strongly linked to ultraviolet (UV) exposure.
Conversely, if first molars were examined in addition to the maxillary incisors, whatever the surfaces considered, the prevalence was about 54 %, close to 56.8 % for all the surfaces examined on all permanent teeth (Table 2).
In any case, whatever the type of evaluation, the prevalence obtained was much higher than that estimated by the caretakers' responses to the questionnaires, and a former study showed that manual and sEMG evaluations were strongly consistent [ 22].
The homogeneity of its prevalence, whatever the country, stream of surveillance or year of detection, contrasts with the epidemiological pattern of classical scrapie.
The prevalence of malnutrition, whatever the type, was higher than in our study for children initiating ART in Malawi, with more than half of children malnourished [ 20].
