Comparison of COVID-19 Cases, Case Rate, and Incidence Rate in Youth Soccer Players Between Clubs at Each Phase of Progression to Return to Soccer

Variable	Individual Training Only (n = 5)	Noncontact, Distanced (n = 49)	Contact, Not Distanced (n = 70)
Total population	5146	28 905	56 956
Total cases	21	58	160
Total person-days	318 591	1 844 041	4 472 963
Cases per 100 000 people	408	201	281
Incidence rate (cases/person-day)a	0.0000785	0.0000369b	0.0000423c,d

^aIncidence rate ratios calculated using unbiased median estimation and mid-P CIs.

^bP = .003 versus individual.

^cP = .008 versus individual.

^dP = .40 versus noncontact.
