Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Treatment 1; Dexamethasone | Swallowing difficulty. Two measurement surveys were used: The Dysphagia Short Questionnaire: An Instrument for Evaluation of Dysphagia (DSQ) and Bazaz Dysphagia Scale (Bazaz). The DSQ and Bazaz determine levels of dysphagia over time after anterior cervical spine surgery. A DSQ score is calculated by summing up the points given for each item to a maximum of 18 points, where lower scores represent milder symptoms (zero indicates no symptoms) and vice versa. For the Bazaz score, symptoms are measured as 'none', 'mild', 'moderate', or 'severe'. Zero indicates none or no symptoms, 1 indicates mild, 2 indicates moderate, 3 indicates severe. Numbers of subjects reporting any difficulty swallowing (had to have a score of at least 1) at various time points are reported. | 0 | 33 | EG000 |
