Registered outcomes10
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Diagnostic Performance of Combined DTF and RSBI for Predicting Extubation Success | 48 hours after extubation | Area under the receiver operating characteristic curve (AUC) of the combined diaphragm thickening fraction and RSBI model compared with RSBI alone for predicting extubation success, defined as no reintubation and no respiratory failure unmanageable with non-invasive ventilation or high-flow oxygen therapy. |
| Secondary | Diaphragm Thickening Fraction | At the beginning and at the end of the spontaneous breathing trial | Right hemidiaphragm thickening fraction measured by ultrasonography, calculated as (end-inspiratory thickness minus end-expiratory thickness) divided by end-expiratory thickness, expressed as a percentage. |
| Secondary | Change in Diaphragm Thickening Fraction During the Spontaneous Breathing Trial | From the beginning to the end of the spontaneous breathing trial | Difference between diaphragm thickening fraction measured at the end and at the beginning of the spontaneous breathing trial, in percentage points. |
| Secondary | Diaphragm Excursion | At the end of the spontaneous breathing trial | Right hemidiaphragm excursion measured by M-mode ultrasonography, in centimeters. |
| Secondary | Rapid Shallow Breathing Index | Before the spontaneous breathing trial | Ratio of respiratory frequency to tidal volume, in breaths/min/L. |
| Secondary | Hospital Mortality | From extubation up to 28 days | Number of participants who died from any cause during the hospital stay. |
| Secondary | ICU Length of Stay | From ICU admission to ICU discharge, assessed up to 28 days | Length of intensive care unit stay, in days. |
| Secondary | Hospital Length of Stay | From hospital admission to hospital discharge, assessed up to 28 days | Total length of hospital stay, in days. |
| Secondary | Reintubation Within 7 Days | 7 days after extubation | Proportion of patients requiring reintubation within 7 days after extubation. |
| Secondary | ICU Mortality | From extubation up to 28 days | Number of participants who died from any cause during the intensive care unit stay. |
