Full Characterisation of Heroin Samples Using Infrared Spectroscopy and Multivariate Calibration
the collected spectral data and PLS modelling. These models were able to identify heroin correctly for 96% of the samples of the external test set with precision, specificity and sensitivity values of ...
Attributing Ethiopian animal health losses to high-level causes using expert elicitation
high-level causes (infectious, non-infectious, and external). Separate in-person workshops were conducted with eight cattle, nine small ruminant, and eight chicken experts. Following the ...
Comparing frailty prevalence between countries: validation of the Global Burden of Disease study Frailty Index (GBD-FI) in the survey of health, ageing and retirement in Europe
generate frailty scores from items available in the Global Burden of Disease study. OBJECTIVE: To externally validate the GBD- FI. METHODS: Data were obtained from the Survey of Health Ageing and Retirement ...
SCORE2-Diabetes: 10-year cardiovascular risk estimation in type 2 diabetes in Europe.
regions. External validation included 217 036 further individuals (38 602 CVD events), and showed good discrimination, and improvement over SCORE2 (C-index change from 0.009 to 0.031). Regional calibration ...
Multidimensional Chromatographic Fingerprinting Combined with Chemometrics for the Identification of Regulated Plants in Suspicious Plant Food Supplements.
DA) through (a) binary modelling and (b) multiclass modelling. The correct classification rates (ccr%) by cross-validation, modelling, and external test set validation were satisfactory for both ...
Methodological considerations in injury burden of disease studies across Europe: a systematic literature review.
European countries. Approximately 79% of injury BoD studies reported the BoD by external cause-of-injury. Most independent studies used the incidence-based approach to calculate YLD s. About half of the ...
Importance of anti-SARS-CoV-2 assay antigenic composition as revealed by the results of the Belgian external quality assessment (EQA) scheme.
divergent results in the Belgian SARS-CoV-2 serology external quality assessment scheme. Sample IS /17575 was serum originating from a 30 years old male patient. 124 diagnostic laboratories analysed this ...

Frequency of Participation in External Quality Assessment Programs Focused on Rare Diseases: Belgian Guidelines for Human Genetics Centers.
Inform, Volume 9, Issue 7 (2021) Abstract: BACKGROUND: Participation in quality controls, also called external quality assessment (EQA) schemes, is required for the ISO15189 accreditation of the Medical ...
An infrared spectroscopic approach to characterise white powders, easily applicable in the context of drug checking, drug prevention and on-site analysis
distinction between amphetamine, cocaine, ketamine and other samples and this with a correct classification rate of 93.1% for an external test set. For quantitative estimation, near-infrared spectroscopy ...
