a community setting. METHODS: A diagnostic accuracy study with prospective data collection, using a two-stage design was conducted in Sinda district of the Eastern province of Zambia between December 2017 and June 2019. ...
Evaluating MIR and NIR Spectroscopy Coupled with Multivariate Analysis for Detection and Quantification of Additives in Tobacco Products.
made between spiked and non-spiked samples for all four targeted additives based on both MIR and NIR spectral data. During supervised analysis, SIMCA achieved 87-100% classification accuracy for the ...
Evaluation of a point-of-care test for the diagnosis of Taenia solium neurocysticercosis in rural southern Tanzania: a diagnostic accuracy study.
study evaluated the diagnostic accuracy of a T solium cysticercosis antibody-detecting lateral-flow point-of-care assay (TS POC test) for the neuroimaging-based diagnosis of neurocysticercosis. METHODS: ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
using the ‘total error’ approach, applying accuracy profiles and conforming to ISO17025. None of the analysed samples exceeded the legal limit for the total amount of ∆9- THC present. However, of the 20 ...
