However, uptake of previous couples' HCT was slightly higher in low HIV prevalence settings than in high HIV prevalence settings, suggesting a need for strata-specific interventions.
At least 10%% more members were retrieved than the sample size needed for each stratum as shown in Table 12.
The rafts were created such that the epidermis did not completely overlap the dermis, thereby allowing spectral measurement of the two strata without need for a confocal setup and increased measurement times.
In the late 1970's and early 1980's, large hydrocarbon discoveries in the Norwegian North Sea in fluvial strata prompted the need for generating geologically meaningful, stochastic, object-based models of fluvial deposits.
We evaluated for each age strata rates of AKI, need for renal replacement therapy (RRT), recovery from RRT, ICU length of stay, hospital length of stay, ICU mortality, hospital mortality, 90-day mortality, and 1-year mortality.
Sample sizes for strata were determined proportional to the number of households residing in each stratum.
The need for more precise correlations of Mesozoic and Cenozoic marine strata in Europe led to the concept of stages, which was introduced in 1842 by French paleontologist Alcide d'Orbigny.
(3) Our review demonstrates the need for temporally and spatially explicit species' data, sampled in strata that reflect environmental gradients across large spatial extents.
Nonetheless, we suggest that future studies addressing the low-income population account for inherent problems of dealing with this stratum, including education limitations (difficulties in understanding certain questions or demands, need for cross-cultural adaptation of the instruments, etc).
To guide policy decisions, there remains a substantial need for data on serotype-specific pneumococcal transmission patterns, pneumococcal pneumonia and invasive disease burden across age strata, and pneumonia and meningitis sequelae.
The need for efficient and cost-effective surveillance systems will induce the use of risk-based selection of hazards and population strata, and risk-based sample size calculation.
