OR, odds ratio; CI, confidence interval.
#Exact Clopper–Pearson confidence intervals.
1p-values < 0.05 are significant and printed in bold.
2Defined as ≥two different HPyVs at baseline.
The risk factors found for MCPyV, HPyV6, HPyV7, HPyV10, and STLPyV in univariable regression analysis were included in a multivariable logistic regression model and remained significant after adjustment for the other covariates.
