(A) Distribution of neutralisation antibody titres in convalescent subjects (n = 296) 6 months after SARS-CoV-2 infection. (B, D, F) Violin plots describing ODR according to neutralising antibody titres. Dotted lines described positive threshold recommended by each manufacturer. Comparisons was performed using the Kruskal Wallis test followed by Dunn's test. ∗∗∗p < 0.001, ∗p < 0.05. (C, E, G) ROC curves were built to estimate the performance of Wantai (C), bioMérieux (E) and Abbott (G) assays for detecting the presence of neutralising antibodies (PRNT50 ≥20, continuous line) and high neutralizing antibody titre (PRNT50 ≥80, dotted line). ODR, optical density ratio; PRNT, plaque reduction neutralization titres.
