  • Analysis was based on 239 cases with bed-sharing status identified (bed sharing: n = 93; non–bed sharing: n = 146). Most variables have missing data. Therefore, for each variable the actual number of cases on which the analysis is based is specified in the denominator of each fraction.

  • a P < .05.

  • b P < .01.
