cord-256568-mbkrg98v	Jantzen, R.	Epidemiological and socio-economic characteristics of the COVID-19 spring outbreak in Quebec, Canada: A population-based study	2020-09-01		.txt	text/plain	7907	419	54	7.6% of the participants declared that they have experienced at least one of the four COVID-related symptoms chosen by the Public Health authorities (fever, cough, dyspnea, anosmia) but were not tested. Results from the tree-based model analyzes adjusted on exposure factors show that the combination of dyspnea, dry cough and fever was highly associated with being tested whereas anosmia, fever, and headache were the most discriminant factors for having a positive test among those tested. A multiple logistic regression analyzis showed that place of residence, dweling, risk exposure (medical worker, contact with a COVID-19 positive patient, international travel), having at least one pre-existing condition were independent factors associated with the outcome ( Table 1) . Taking into account socio-demographic, medical and exposure factors (place of residence, dweling, medical worker, contact with a COVID-19 positive patient, international travel, pre-existing condition) as confounding factors and COVID-related symptoms as explanatory variables, we performed a GPLTR analyzis for identifying the combinations of symptoms leading to the most homogeneous sub-groups with respect to being tested.	./cache/cord-256568-mbkrg98v.txt	./txt/cord-256568-mbkrg98v.txt
