Secretor status COVID‐19 associations

Model	COVID‐19 association	N	N‐phenotype (+)	N‐phenotype (−)	N‐diagnosis (+)	N‐diagnosis (−)	OR (95% CI)	p‐value
Secretor	susceptibility	97,494	78,140	19,354	5822	91,672	1.035 (0.968–1.107)	.318
Secretor	Severity	5430	4379	1051	133	5297	0.680 (0.458–1.033)	.14 E−02

Note: Cohort tally and results from the logistic regression model exploring the effect secretor status on COVID‐19 susceptibility, severity, and symptom length. N‐diagnosis tallies the number of persons in the cohort with (+) or without (−) the given diagnosis. The diagnosis in question is denoted in the COVID‐19 association column. N‐phenotype tallies the number of persons with (+) or without (−) a given phenotype. The phenotype in question is denoted in the first column.
