Table includes independent variables associated with salivary shedding at p ≤ 0.10. Parameter estimates and significance tests are from logistic regression with generalized estimating equations.

^aNo. of visits with salivary shedding/total visits (percent).

^bP-value for trend.

^cORs for continuous variables are based on a one-unit change in the predictor; for study visit, one-unit change = 6 months.

^dMedian (IQR) by salivary shedding status.
