  1. Outcome was assessed using multivariate logistic regression estimating odd ratios (ORs) and 95% confidence intervals (CIs). Crude and adjusted odds ratios determine the factors associated with the use and the visual correct positioning of facemask fit. Values presented as number (%). p < 0.05 was considered statistically significant. The multivariate model had no missing data
