Note. PSQI: pittsburgh sleep quality index, good sleeper had a PSQI <5 and a poor sleeper had a PSQI ≥5; CPC: cardiopulmonary coupling analysis, a stable sleep ratio ≥41% indicates adequate sleep stability and a stable sleep ratio <41% indicates inadequate sleep stability; ^#Work pressure measured by questionnaire of medical worker’s stress (QMWS). Multiple variable logistic regression was used for statistical analysis.
