Factors associated with SARS-CoV-2 infection. Forest plots show factors associated with infection in (A) Rutgers Corona Cohort participants (n = 831) and (B) the subset of healthcare workers (n = 548) as measured by positive SARS-CoV-2 PCR or antibody testing. Results reflect aORs from multivariable logistic regression models fitted with elastic net penalty for regularization and variable selection from among variables listed in Table 1. Reference groups included: age < 40 years (versus ≥ 60 years), white race (versus Asian race), and attending physician (vs nursing). Abbreviations: aOR, adjusted odds ratio; CI, confidence interval; ICU, intensive care unit; OR, operating room; PCR, polymerase chain reaction; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
