Cox regression survival estimates for 150 patients with COVID-19 sampled for nAb response to SARS-CoV-2 during in-hospital visit. The analysis was adjusted for sex and age and stratified for the time from symptoms onset at serum sampling. In (a) the time to a SARS-CoV-2 negative naso-pharyngeal swab (HR 2.238, 95%CI 1.342–3.734; p = 0.002) and in (b) the survival rate (HR 2.918, 95%CI 1.321–6.449; p = 0.008) was estimated by the presence or absence of a nAb response. Dots represent the Hazard Ratio (HR), filled dots stand for p < 0.05 (two-sided). Wald statistics were used for comparison. Source data are provided as a Source Data file.
