Data are point prevalence rates and prevalence odds ratios (POR) and prevalence ratios (PR) with 95% confidence intervals (CI). Adj. POR and PR are adjusted based on age.

*95% CI does not overlap null value of 1.0.

^† p < 0.05 vs. Neither within a given parasomnia; chi-square with Bonferroni post hoc analysis.
