Design outcomes

Primary

Measure	Time frame
Primary outcomes were the new-onset of sleep disorder (PSQI >5) or frequency of nocturia >1 and the changes of nocturia and PSQI for 5 years.	—

Secondary

Measure	Time frame
Secondary outcomes included the bidirectional relationships between sleep disorder and nocturia between the baseline and 5-year follow-up. A cross-lagged panel analysis was performed to analyze the bidirectional association between sleep disorder and nocturia.	—
