The case group will consist of patients who develop coughing before extubation (N=112), while the control group will comprise those without coughing before extubation (N=112).\n\nData to be collected include general demographic characteristics, smoking and smoking cessation history, comorbid conditions (with particular attention to snoring during sleep and sleep apnea-hypopnea syndrome \\[SAHS\\]), history of pulmonary diseases, mode of spontaneous breathing, surgical and anesthetic data, as well as blood pressure and heart rate before, during, and after extubation, pain scores, and sedation levels.\n\nContinuous variables will be presented as mean ± standard deviation (for normally distributed data) or median with interquartile range (IQR) (for non-normally distributed data). Categorical variables will be described using frequencies and percentages (e.g., sex, smoking history). Baseline differences between the case and control groups will be compared using the chi-square test (for categorical variables), Student's t-test (for normally distributed continuous variables), or the Mann-Whitney U test (for non-normally distributed continuous variables). Multivariable logistic regression analysis will be employed to evaluate the independent association between the mode of spontaneous breathing and coughing before extubation, with adjustment for potential confounding factors, and odds ratios (ORs) with their 95% confidence intervals (95%CI) will be calculated. All statistical analyses will be performed using SPSS or R software.",[24,25],"Coughing Responses at Tracheal Extubation","Breathing Patterns",[27,28,29,30],"Oronasal Breathing Pattern","Endotracheal Tube Intolerance","Emergence from General Anaesthesia","Nested Case-Control Study","NOT_YET_RECRUITING","2026-08-11",{"date":34,"type":35},"2026-08-12","ACTUAL",{"date":37,"type":20},"2026-09-01",{"date":39,"type":20},"2026-10-31",{"name":41,"class":42},"Peking University People's Hospital","OTHER",{"id":44,"slug":45,"hasResults":11,"nctId":46,"briefTitle":47,"officialTitle":48,"acronym":4,"eligibilityCriteria":49,"healthyVolunteers":16,"sex":17,"minAge":50,"maxAge":4,"enrollmentInfo":51,"targetDuration":4,"studyType":21,"phases":4,"briefSummary":53,"conditions":54,"keywords":56,"overallStatus":31,"whyStopped":4,"lastUpdateSubmitDate":61,"lastUpdatePostDateStruct":62,"startDateStruct":64,"completionDateStruct":66,"leadSponsor":68,"locationsCount":4},"100610540","respiratory-and-anxiety-status-of-music-students-100610540","NCT07228910","Respiratory and Anxiety Status of Music Students","Relationship Between Dysfunctional Breathing, Respiratory Patterns, and Performance Anxiety in Music Students","Inclusion Criteria:\n\n* Being a student of music department\n* Playing an instrument for at least 1 year\n* Volunteer\n\nExclusion Criteria:\n\n* Having any respiratory disease (Asthma , COPD etc.)","18 Years",{"count":52,"type":20},233,"This study aims to determine the prevalence and patterns of dysfunctional breathing (DB) among music students and to investigate its relationship with music performance anxiety (MPA).

Given that MPA is common among musicians and often accompanied by symptoms such as palpitations, tremor, and shortness of breath, this study explores whether DB contributes to or is influenced by performance-related anxiety in this population.",[55,25],"Dysfunctional Breathing",[57,58,59,60],"Dysfunctional breathing","Breathing patterns","Music students","Music performance anxiety","2025-11-13",{"date":63,"type":35},"2025-11-14",{"date":65,"type":20},"2025-12-01",{"date":67,"type":20},"2026-01-31",{"name":69,"class":42},"Pamukkale University"]
