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 ...

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 ...
Validity of self-reported mammography uptake in the Belgian health interview survey: selection and reporting bias.
assessed the related selection and reporting biases among women aged 50-69 years in the Belgian Health Interview Survey (BHIS) using reimbursement data for mammography stemming from the Belgian Compulsory ...
