Note. BL = preintervention baseline; IRR = incident rate ratio; ITT = intent to treat; PVI = pandemic vulnerability index; SARS-CoV-2 = severe acute respiratory syndrome coronavirus 2. Multilevel models are generalized linear negative binomial for count and categorical data and multilevel linear models for scale score data. Multilevel models adjust for the nonindependence of participants clustered in randomized testing events by appropriately estimating SEs.
aOutcome modeled using a normal distribution.
bOutcome modeled using a negative binomial distribution.
cModerator analysis conducted separately from main effects.
dModerator analysis conducted separately from main effects; Latinx removed from model because of multicollinearity with Spanish language.
