The duration of viral RNA shedding and the titers of specific IgG and IgM in the three groups with hypertension. A. The average duration of viral RNA shedding was lower in the FV and PV groups with hypertension than in the UV group with hypertension although the difference was not statistically significant (P = 0.065). B. The median titer of SARS-CoV-2-specific IgG was significantly higher in the FV group with hypertension than in the UV group with hypertension (adjusted P < 0.001). The median titer of SARS-CoV-2-specific IgG was higher in the PV group with hypertension than in the UV group with hypertension although the difference was not statistically significant (adjusted P = 0.113). C. The titers of SARS-CoV-2-specific IgM were significantly higher in the FV and PV groups with hypertension than in the UV group with hypertension (adjusted P = 0.035 and adjusted P = 0.027, respectively). D. Cumulative proportion of patients with detectable SARS-CoV-2 RNA by days after the illness onset between the UV, PV, and FV groups with hypertension. Continuous variables were analyzed by variance analysis or Kruskal‒Wallis test. Kaplan‒Meier survival analysis was used to estimate the cumulative SARS-CoV-2 RNA negativity rate. A P value of less than 0.05 (two-tailed) was considered statistically significant. FV fully vaccinated, PV partially vaccinated, UV unvaccinated; SARS-CoV-2 Severe Acute Respiratory Syndrome Coronavirus 2, IQR interquartile range
