The age difference is most likely due to our targeted sampling procedure in which the red hair color category was over-sampled in young individuals (see material section for further details).
Work is ongoing to evaluate targeted sampling that is expected to significantly reduce time commitment to taking CSNTs.
In each of three locations — Kiev, Odessa, and Makeevka/Donesk — 100 IDUs were recruited using modified targeted sampling methods.
The lack of resolution in most multigene analyses, including phylogenomic analyses, necessitates a search for additional, appropriate molecular markers to enable targeted sampling of taxa in key phylogenetic positions.
The benefit of placing Kiehl's in a hotel such as the Soho Grand is "targeted sampling," says Schiller.
Outreach recruitment followed a targeted sampling plan, which was developed for HIV prevention studies and has been used to recruit a convenience sample of those at increased risk for HIV [44], [45].
For recruitment, targeted sampling and nomination techniques, with different starting points mainly in outdoor locations, was used[ 28].
BD102 did not show any pathological modifications in the lung, a fact that did not allow targeted sampling.
We recruited PLHIV through non-probability targeted sampling using CHWs to reach potential participants, which might have introduced selection bias.
The demographic characteristics of those agreeing to take part were determined and further targeted sampling undertaken to ensure the study sample remained representative.
We have shown how systematic errors in the demographic characterisation of network data, resulting from targeted sampling procedures, can bias the picture of between-host network connectivity.
