We projected the entire quantity of affirmed COVID-19 instances for every step 1,000 employed anybody into a few crisis swells for each from the occupation teams. age. an excellent categorical variable for instance the 22 groups, you to each occupation) and outcome ‘affirmed COVID-19′ (yes/no) having fun with logistic regression alone each of surf and reporting chance rates (OR). Up coming, we believed that several potential covariates get mistake this new organization between profession and you will trend-particular COVID-19 lead, so we modified for the following covariates in around three multivariate logistic regression activities: (i) ages and you can sex, (ii) age, sex, nation off delivery and mom’s country regarding beginning (as sign might have been considered such as packed with immigrant groups ) and you will (iii) age, sex, nation out-of delivery, mom’s country out of beginning and you can marital condition.
