- FIB, frequency of irregular bedtime; ADST, average daily sleep time; ESS, Epworth Sleepiness Scale; FSS, Fatigue Severity Scale; PSQI, Pittsburgh Sleep Quality Index; r, correlation coefficients.
- The multivariate regression analysis was performed by setting the intermediate and high FIB groups as dummy variables in comparison to the low FIB group
- *p < 0.05
