Second, deficits that were too saturated were excluded to prevent ceiling effects, using a prevalence cut-off of 80%%.
Countries were grouped into low, intermediate, and high HBsAg and anti-HCV-Ab prevalence using cut offs of ≤ 1%, > 1% to ≤ 2%, and > 2%.
The average prevalence between cut points at baseline ranged from 17.9% by Morris/Gulati sex-specific age-predicted equations to 55.1% by Morris/Gulati sex-specific age-predicted cut points for participants with increased risk of CVD (≥85%).
They reported a prevalence of cut-out of 7%.
The prevalence of cut-out failure in this large consecutive series of 3066 proximal femoral fractures was 1.85% (57 patients).
Likewise, when using the index in populations with a different prevalence, the cut-off is optimal with reference to a different cost ratio.
It has been argued that local cut-off values need to be established, and for Denmark, a low prevalence country, a cut-off for the IgM phase II Focus Diagnostics IFA of ≥1 256 was suggested [ 24].
Cutting prevalence from 5.1 to, say, 3 is practically important and consistent with the findings of the study.
It's a track that in many ways is difficult to remix, due to the prevalence of quick cuts, and a complex arrangement of sounds and vocal bits.
Accordingly, in a context of high prevalence, a low cut-off value could therefore be used (for example 30% OD).
Analyses performed on data from northern European registers only partially fill this gap since there is a clear-cut prevalence of cemented prostheses with metal-polyethylene couplings.
