	Nocturia number	0.146	0.038	0.345	−0.157 to 0.449
	PSQI score	0.186	0.135	0.001*	0.077 to 0.295a
PSQI score	Age	0.019	0.072	0.049	0.000 to 0.039
	Sex	−2.311	−0.275	0.000*	−2.886 to −1.737a

Notes: For the parameter of sex, we define male as 1 and female as 0.

^a95% confidence interval does not cover zero.

^*P-value >0.05.
