19/9/2020· The potential effect of house screening in reducing malaria prevalence and incidences has been demonstrated in other related studies in Africa [21, 23, 46, 47, 51, 53]. A randomized trial in the Gambia also showed that screening was effective in reducing the level of anaemia in children [ 23 ] and in Dar es Salaam Tanzania, house screening contributed to a reduction in malaria transmission ...

12/6/2020· The lack of locally validated screening instruments contributes to poor detection of depression in primary care. The Patient Health Questionnaire-9 (PHQ-9) is a brief and freely available screening tool which was developed for primary care settings; however, its accuracy may be affected by the population in which it is administered. This study aimed to determine the validity and reliability of ...
Thus, a 15% cut point provides a reasonable buffer allowing for variance between risk assessment models (Ozanne, 2013). Screening tools to guide referral The five tools in this study were recommended by the USPSTF as primary screening tools to identify patients at increased risk for breast cancer due to family history ( Moyer, 2014 ).
Close inspection of simulated and real score distributions from virtual screening, however, suggests that 'analysis of variance' (ANOVA) is a more reliable method for assessing their performance.

During the screening design, the stator configuration was deemed as fixed, reacting the same in each experiment. The stator configuration was chosen for testing based on an analysis of historical data, where the shape of the stator had a great impact on the noise level of the alternator.
1/3/2020· The conventional Design A (an H-design appended by center points) and a proposed Design B (the projection of a larger H-design) are under study. The main conclusion is that compared with Design A, Design B typically achieves a more reliable estimate of σ 2, denoted by σ ˆ 2 .

Design of Experiments, or DOE, is a tool to develop an experimentation strategy that maximizes learning using a minimum of resources. Design of Experiments is widely used in many fields with broad application across all the natural and social sciences.
The short and screening versions of the ZBI produced results comparable to those of the full version. Reducing the number of items did not affect the properties of the ZBI, and it may lead to easier administration of the instrument.
Background: Survey data used to study trends in cancer screening may overestimate screening utilization while potentially underestimating existing disparities in use. Methods: We did a literature review and meta-analysis of validation studies examining the accuracy of self-reported cancer-screening histories. We calculated summary random-effects estimates for sensitivity and specificity ...
