According to Walker-Hertkorn (personal communication 2017), the proportion of vertical systems is about 80%.
Compared with 2007, the increase in ARV uptake for PMTCT (from 33% to 57%) and the switch to more efficacious ARV regimens likely will substantially increase the proportion of vertical infections averted (from 8.1% to 18.1%).
Although changes in HIV prevalence would affect the absolute size of estimates (e.g., number of vertical infections), they would have little impact on the relative effects (e.g., proportion of vertical infections averted) of ARV-PMTCT or FP and hence would not change the overall findings and conclusions.
A much larger proportion of vertical support is channeled directly to NGOs that center on specific projects whose funding, planning, and implementation are conducted outside the MOH.
Fig. 3 displays the relative proportion of vertical inheritance (in blue) and of lateral transfer (in orange), phylogenetically assessed for each node of the synthesis.
This high proportion of vertical topologies for the paralogous two taxon case suggests that LGT of these genes between the higher level taxonomic groups sampled here is quite rare, whereby this result does not address the frequency of transfer of these genes among closely related lineages.
The proportions of these vertical flags are not specified.
The lowest proportion of all vertical infections was estimated to occur in Frontier governorates (0.9%).
Hence, finding some proportion (say one-third) for a given angle (here ∠COA) is simple: find the equal proportion for vertical displacement of the point on the quadratrix at which the two segments intersect (C), locate the point (F) on the quadratrix at that height (one-third of the original height in this example), and then draw the new angle (∠FOA, indicated in blue) through that point.
The proportions of the stairwell and its vertical lines create a cohesion between the third floor and the fourth floor, where executive offices and administrative services are found.
