As per the univariate analysis linked to sleep disorder (PSQI-J score 6 or greater) for all cases, age (p = 0.0111), and frailty score (p < 0.0001) were found to be significantly associated with sleep disorder, while ALBI score (p = 0.0825) and serum albumin (p = 0.0708) tended to be significant (Table 2). Here, ALB is linked to sleep disorder.
