Furthermore, the limited sensitivity of tuberculin skin test may have under-estimation of the true prevalence of LTBI however; we believe that this is a valuable addition to the few existing population-based estimates of prevalence of LTBI in this urban setting.
Astronomers estimate that 1,800 2,200 of the total existing population of Jupiter's Trojans have diameters greater than 10 km (6 miles).
Some cost estimates are made on the basis of the existing population data on health care use, disability and mortality, while others are performed using the data of patients with DM at an individual level.
In particular, Google or other vendors of smartphone operating systems can easily leverage on an existing population of suitable devices to collect raw data for computing travel time estimates.
Numerous applications of the existing population maps are planned to exploit the increased spatial resolution, including the refinement of malaria risk and burden estimates [26], health system commodity estimation and medical facility accessibility modelling [18].
It would also have facilitated a better comparison with the existing US population estimates.
"Of the nine existing populations of Sumatran orangutans, only seven have prospects of long-term viability, each with an estimated 250 or more individuals," states WWF.
There are no reliable estimates of prehistoric megafauna populations, so the best we can do is extrapolate from existing populations.
Furthermore, variation in existing, population-level immunity to specific strains, and the use of different case ascertainment methods in specific studies also inevitably skew estimates made using either procedure.
Total population estimates are compared against existing estimates in Figure 5. *indicates figures not based on Bayesian analysis where CI refers to Confidence Intervals We produced four estimates of the UK owned-dog population using combinations of the public survey with other information sources.
