Fig. 2: Distribution of neutralising antibody (NAb) levels in % by surrogate virus neutralisation test (sVNT) in different periods from the onset date, among 490 measurements in 200 patients.

Violin plot with box plot (light grey marker for median and box for interquartile range) showing the distribution of neutralising antibody (NAb) levels in % by periods from the onset date: within 3 months (208 measurements), above 3 months – 6 months (110 measurements), above 6 months – 9 months (99 measurements), and above 9 months (73 measurements); note: 1 patient may have more than one measurement in the same period.
