SPSS for Windows Version 17.0 software was used to perform data
analysis in this study. Before analysis, all data were examined to ensure
accuracy and identify missing values. Descriptive analysis was
employed to examine the demographic data. The data and distribution
of each parameter are expressed using frequencies, percentages, averages, and standard deviations (SDs). The paired t test, Pearson's correlation test, and multiple linear regression were performed to ascertain the
relationship between subjective and objective sleep data.
