The individual results of SARS-CoV-2 serological tests measured after the first pandemic wave 2020 cannot be directly interpreted as a probability having been infected. Plus, these are usually returned binary or ternary variable, relying on predefined cut-offs. We propose Bayesian mixture model to estimate infection probabilities, based 81,797 continuous anti-spike IgG from Euroimmun collected in France wave. This approach used and was therefore not diagnostic Cumulative incidence, which is...
Background and Purpose— One-third of ruptured aneurysms are located on the anterior communicating complex with high prevalence anatomic variations this arterial segment. In study, we hypothesized that increase risk angiographic vasospasm. Methods— Retrospective study prospectively collected data from a monocentric subarachnoid hemorrhage cohort patients admitted to neurointensive care between 2002 2018. Univariate followed by multivariate logistic regression analysis was used identify...
Des épisodes de surcharge hospitalière, pouvant nuire à la qualité des soins, ont eu lieu dans nombreux pays durant première vague COVID-19. Plusieurs études ainsi suggéré une association entre l'incidence locale COVID-19 (donc charge hospitalière) et le risque décès personnes infectées (IFR : infection fatality rate). En particulier, négative nombre lits soins intensifs par cas létalité exprimée en CFR (case rate) avait été retrouvée aux États-Unis vague. Notre objectif était d'explorer...
Abstract Several studies found an association between the risk of death for COVID-19 patients and hospital overload during first pandemic wave. We studied this across French departments using 82,467 serological samples a hierarchical Bayesian model. In high-incidence areas, we hypothesized that would increase infection fatality rate (IFR) without increasing hospitalization (IHR). departmental incidence from 3% to 9% rose IFR 0.42% 1.14%, IHR 1.66% 3.61%. An in 6% 12% people under 60 was...
Abstract COVID-19 serological tests with a “positive”, “intermediate” or “negative” result according to predefined thresholds cannot be directly interpreted as probability of having been infected SARS-CoV-2. Based on 81,797 continuous anti-spike collected in France after the first wave, Bayesian mixture model was developed provide tailored infection for each participant. Depending value and context (age administrative region), negative positive test could correspond high 61.9% low 68.0%,...
