The data layer: the importance of sources critical appraisal
is to tracking the health status of its citizens and understanding its evolution over time. Given the absence of a singular, comprehensive data source, we developed a framework to select databases ...
Accuracy of immunological tests on serum and urine for diagnosis of Taenia solium neurocysticercosis: A systematic review
localization and stage according to a developed confidence scale, and with selection of tests evaluated on a sufficiently high sample size. A QUADAS-2 risk of bias assessment was performed. After screening, 169 ...
An interlaboratory proficiency test using metagenomic sequencing as a diagnostic tool for the detection of RNA viruses in swine fecal material.
classifier as well as read mapping to selected astroviral reference genomes to assess the semiquantitative representation of astrovirus species mixtures. All participants successfully identified and classified ...
Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling
samples during an outbreak investigation requires the samples to be enriched in order to reach detectable levels. However, a bias can occur during the enrichment of the food due to competition between the ...
Evaluating methodological approaches to assess the severity of infection with SARS-CoV-2 variants: scoping review and applications on Belgian COVID-19 data.
categorization of patients based on time periods). Different potential selection biases (e.g., overcontrol bias, endogenous selection bias, sample truncation bias) and factors fluctuating over time (e.g., medical ...
Severity of infection with the SARS-CoV-2 B.1.1.7 lineage among hospitalized COVID-19 patients in Belgium.
analyses were performed to assess the influence of selection bias, vaccination rollout, and unmeasured confounding. RESULTS: We observed no difference between the exposed and unexposed group in severe ...
Selection and use of reference panels: a case study highlighting current gaps in the materials available for foot and mouth disease.
are required. These are to: reduce bias in estimates of the diagnostic sensitivity and inter-serotypic specificity of tests used to detect diverse strains of FMD virus (FMDV), provide bio-safe positive ...
Psychological distress associated with the COVID-19 pandemic and suppression measures during the first wave in Belgium
Health Interview Survey of 2018. Bootstrapping was performed and analyses were reweighted to match the Belgian population in order to control for survey selection bias. Results Half of the respondents ...
Conceptual causal framework to assess the effect of SARS-CoV-2 variants on COVID-19 disease severity among hospitalized patients
assumptions on the relationship between (confounding) variables are made explicit. Various DAG s are presented to explore specific study design options and the risk for selection bias. Next, the data ...
Selection and use of reference panels: a case study highlighting current gaps in the materials available for foot and mouth disease
an example, this review highlights four specific areas where new reference reagents are required. These are to: reduce bias in estimates of the diagnostic sensitivity and inter-serotypic specificity of ...
