Does drug‐induced sleep endoscopy affect surgical outcome? A multicenter study of 326 obstructive sleep apnea patients
Bibliographic record
Abstract
OBJECTIVES/HYPOTHESIS: Our objective was to determine whether drug-induced sleep apnea (DISE) affects the successfulness of the surgical outcome. STUDY DESIGN: Prospective, seven-country, nonrandomized trial. METHODS: There were 326 consecutive obstructive sleep apnea (OSA) patients who had nose, palate, and/or tongue surgery included in the study. DISE was performed in only one group. RESULTS: There were 170 patients in the DISE group and 156 patients in no-DISE group. The mean preoperative body mass index (BMI) for the DISE group was 27.6 ± 4.6, whereas in the no-DISE group it was 28.1 ± 3.9 (P = .23). The mean preoperative systolic blood pressure (SBP) for the DISE group was 130.4 ± 16.7, whereas in the no-DISE group it was 142.9 ± 15.5 (P < .001). The mean preoperative diastolic blood pressure (DBP) for the DISE group was 81.4 ± 9.7, whereas in the no-DISE group it was 89.1 ± 9.7 (P < .001). The mean preoperative apnea-hypopnea index (AHI) for the DISE group was 32.6 ± 18.8, whereas in the no-DISE group it was 33.7 ± 19.6 (P = .61). The mean postoperative AHI for the DISE group was 15.9 ± 12.6, whereas in the no-DISE group it was 13.2 ± 8.8 (P = .023). The age-, gender-, BMI-adjusted percentage change in AHI for the DISE group was -48.4 ± 31.9, whereas in the no-DISE group it was -59.8 ± 18.6 (P < .001). The age-, gender-, and BMI-adjusted success rate for the DISE group was 66.5%, whereas in the no-DISE group it was 80.8% (P = .004). The age-, gender-, and BMI-adjusted change in SBP for the DISE group was -6.1 ± 8.6, whereas in the no-DISE group it was -13.3 ± 11.1 (P < .001). The age-, gender-, and BMI-adjusted change in DBP in the DISE group was -5.2 ± 12.1, whereas in the no-DISE group it was -12.4 ± 11.7 (P < .001). The mean age- and gender-adjusted change in BMI for the DISE group was -4.6 ± 12.9, whereas in the no-DISE group it was -6.3 ± 18.5 (P = .34). The Cohen effect of BMI on the overall AHI, lowest oxygen saturation, and blood pressure changes was 0.08. CONCLUSIONS: DISE may not significantly affect surgical success in OSA. LEVEL OF EVIDENCE: 2c Laryngoscope, 130:551-555, 2020.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
