Interim analysis of COVID-19 vaccine effectiveness against hospitalisation and death using electronic health records in six European countries
estimates against COVID19-related mortality were similar, although estimates had high uncertainty due to a low number of events, particularly in the groups <65 years. Compared to complete primary ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
detection, working range, selectivity, precision, trueness, robustness, and ruggedness. An uncertainty that was associated to intermediate precision in the range of 1–7% and an expanded measurement uncertainty ...
Scientific opinion on the proposed amendment of the EU specifications for titanium dioxide (E 171) with respect to the inclusion of additional parameters related to its particle size distribution
a median minimal external dimension below 100 nm, should be inserted in the current EU specifications. The Panel considered that the conclusions made, and the uncertainties identified, in the previous EFSA ...

Measurement uncertainties of size, shape, and surface measurements using transmission electron microscopy of near-monodisperse, near-spherical nanoparticles
nanoparticles Measurement uncertainty Nanometrology Health Topics: Health and environment Santé et environnement Gezondheid en milieu Service: Éléments traces et nanomatériaux Spoorelementen en nanomaterialen ...
Dietary exposure of the Belgian adult population to non-dioxin-like PCBs.
followed by dairy products (28.5%). As neither EFSA nor JECFA have set a Tolerable Daily Intake for ndl PCB s, uncertainty remains about how to interpret the exposure data in terms of public health. Health ...
Comment estimer l'incertitude de mesure lors de la quantification de pesticides?
PAR PAS pesticide Pesticides Quantification uncertainty Abstract: Pour evaluer l’incertitude de mesure sur la concentration d’un pesticide, plusieurs approches peuvent etre envisagees pour autant ...
Accuracy profiles assessing the validity for routine use of high-performance thin-layer chromatographic assays for drug formulations
uncertainties of every compound at each concentration level could also be determined from the accuracy profile data Service: Geneesmiddelen en gezondheidsproducten Medicines and health products Médicaments et ...
A validated GC-MS method for the determination and quantification of residual solvents in counterfeit tablets and capsules.
β-expectation tolerance limits did not exceed the acceptance limits of ±10% and the relative expanded uncertainties were acceptable for all of the considered components. A method was obtained for the screening ...
Scientific Opinion of the EFSA Panel on Plant Protection Products and their Residues (PPR), Guidance on the use of probabilistic methodology for modelling dietary exposure to pesticide residues
Technique Type uncertainty use VARIABILITY work Abstract: The European Food Safety Authority (EFSA) asked the Panel on Plant Protection Products and theirResidues to provide guidance on methodology for ...
