None of the variables were significantly associated with HPV 16 discordance at α = 0.05 level.
Unadjusted odds ratio calculated using simple logistic regression.
95% confidence interval.
Adjusted odds ratio; was calculated using multivariable logistic regression with weakly informative default prior distribution for the regression coefficients. Model was adjusted for country of residence, age, education, marital status, cigarette smoking status, using chewing tobacco or snuff, alcohol consumption and sexual orientation.
95% Bayesian credible interval; an interval within which an observed parameter value falls with 95% probability.
Weakly informative prior distribution was applied via naïve Bayesian logistic regression model since simple logistic regression yielded infinitely wide confidence intervals.

MSM: Men Having Sex with Men.
MSMW: Men having Sex with Men and Women.
