From: A stronger antibody response in increased disease severity of SARS-CoV-2
Probability of IgG-S1 antibodies persisting according to severity in 238 individuals who recovered from COVID-19 over 386 days. (Kaplan Meier Curve: Log Rank (Mantel-Cox): Chi-Square 10.1575 df 1 p = 0.001 Testing equality of survival distributions for the different levels of Hospitalization.). There was a greater probability of IgG-S1 antibody persisting over time among samples from hospitalized individuals when compared to samples from non-hospitalized participants (p = 0.001)
