Extended Data Fig. 3: Neutralization titres in B.1.1.7 infected individuals with/without dexamethasone treatment.
a) Comparison of the cross-neutralizing activity between 0-3 (black, n = 19) and 4-5 (red, n = 13) severity groups for B.1.1.7 infected individuals who had not yet received dexamethasone treatment at the time of serum sampling. Difference between 0-3 and 4-5 disease severity groups was calculated using a Mann–Whitney two-sided test U-test and showed no significant differences. b) Comparison of the cross-neutralizing activity for sera from B.1.1.7 infected individuals experiencing 4-5 disease, either having received (blue, n = 29) or not received (black, n = 13) dexamethasone treatment. Difference between treated and untreated groups were calculated using a Mann–Whitney two-sided test U-test and showed no significant differences.
