Data on bed partners and usage of antidepressants was not a part of this analysis. RBD screening questionnaire scores and MDS UPDRS III scores were categorized for the purpose of analysis. Details have been discussed in the manuscript.

Our analysis showed a statistically significant difference in the percentage of males between the two groups. There was no significant difference in the GDS-indicated depression percentage and age between the two groups.
