  1. ap Values compare PCR-positive case patients to PCR-negative control patients for the specified demographic/co-morbidity. Analyses were performed using Pearson’s chi-squared with α = 0.05. bCramer’s V results are based on absolute value. Values < 0.1 represents little to no association with the test groups. cHospitalization represents if a patient was hospitalized in the 30–120 time period post index date. dDeath represents if a patient died 0–120 days post index.
