Primary outcomes: primary, sensitivity and supplementary analyses.
ASYMPTOMATIC COVID-19
The primary outcomes of symptomatic (upper panels) and severe (lower panels) COVID-19 are shown using Kaplan-Meier curves with 95% confidence intervals (unadjusted primary analyses; left panels). Forest plots denote difference in percent with symptomatic COVID-19 with 95% confidence intervals (adjusted for stratification factors used in randomisation - primary, sensitivity, and supplementary analyses; right panels). Confidence interval widths have not been adjusted for multiplicity and may not be used in place of hypothesis testing.
