However, it is not possible to conclude from these results that obesity is an independent factor of mortality for patients infected with COVID-19 due to the small sample sizes of these studies, neither to have a precise estimate of obesity size effect due to the absence of BMI categories and incomplete follow-up. We imputed missing BMI category using predictive mean matching considering as the following as explaining variables: comorbidities (hypertension, diabetes, sleep apnea, dyslipidemia, chronic kidney disease, heart failure, cancer), smoking status, sex, age and indirect information regarding BMI value (obesity from free-text reports, variables extracted from 4-digits E66 ICD-10 codes and malnutrition ICD-10 codes).	./cache/cord-261891-yiiz9s53.txt	./txt/cord-261891-yiiz9s53.txt
