Table 4.
Continuous laryngoscopy exercise (CLE) scores from the 45 patients included from the EILO register at Haukeland University Hospital, Bergen (Norway) who were surgically treated for EILO during 2013–2015a.
| CLE conditions | Pre-operative | Post-operative | Pre-post change | |
|---|---|---|---|---|
| Mean (SD) | Mean (SD) | Mean (SD) | 95% CI | |
| MODERATE INTENSITY | ||||
| Glottic (CLE A) | 0.27 (0.49) | 0.09 (0.36) | 0.18 (0.44) | (−0.08, 0.43) |
| Supraglottic (CLE B) | 1.18 (0.96) | 0.49 (0.73) | 0.69 (0.73) | (0.43, 0.94) |
| MAXIMUM INTENSITY | ||||
| Glottic (CLE C) | 1.51 (0.92) | 0.84 (0.93) | 0.67 (0.93) | (0.41, 0.92) |
| Supraglottic (CLE D) | 2.42 (0.54) | 0.93 (0.78) | 1.49 (0.81) | (1.23, 1.74) |
| Sum score (CLE E) | 5.38 (2.07) | 2.36 (1.85) | 3.02 (1.60) | (2.54, 3.50)b |
CLE A, glottic obstruction at moderate intensity; CLE B, supraglottic obstruction at moderate intensity; CLE C, glottic obstruction at maximum intensity; CLE D, supraglottic obstruction at maximum intensity; CLE E, sum-score (A + B + C + D), see Figure 1 for illustrations on CLE score; CI, confidence interval; SD, standard deviation.
In the final mixed linear regression model: CLE-score = constant + surgery + Intensity + location + surgery*Intensity + surgery*location, where all included effects were significant (p < 0.001).
Estimates from Student's paired t-test, p < 0.001.
