Despite this, BP data from 23% of participants were invalid, mainly due to artefact from external pressure on the finger cuff at the time of standing or due to a poor quality trace.
The remaining 1140 clones produced only poor quality traces or showed evidence of contamination.
Moreover, the lost cases in our context had probably been dead but were not reported due to poor patient tracing and reporting mechanisms of the recent scaled up services of the study facilities.
Design of primers fitting the bisulfite treatment requirements for a hexaploid genome was not trivial, and about 50% of the PCR designed were either not amplifying or leading to poor sequencing traces.
For the rating of "feasibility" of items to address, the clusters with the highest rating values were Resources Needed for Effective Tracing, Poor Documentation, and Health Worker Issues Related to Tracing.
Another limitation was the number of poor-quality traces obtained, although the sample size used was sufficient to ensure that the minimum evaluable data required to achieve adequate statistical power were obtained.
In this study, we only analyze sediment finer than 63 μm, and we inferred that the coarser material may be dominated by quartz, feldspar, and other minerals, which are relatively poor in many trace elements.
The recently revitalized Rapid Alert program at WHO has begun to "track and trace" poor quality drugs as reported voluntarily by member countries.
Comparison with numbers of holdings recorded in each county by the agricultural survey showed that tracing from Shetland, the Western Isles and Highland was poor, but that tracing from other counties was relatively uniform.
The imposition of obligations on communities to pay taxes in order to provide for the poor can be traced back for hundreds of years in a number of different societies.
