<p><strong>Purpose: </strong>since about only 30% of polysomnography results confirm the indications, it would be useful to identify clinical data predictive of positive results. The objective is to evaluate the correlation between clinical data and polysomnography findings in a cohort of patients. </p><p><strong>Methods:</strong> 237 polysomnographies and the related clinical data from 226 patients were evaluated retrospectively.</p><p><strong>Results:</strong> the clinical suspicion and the polysomnography findings presented a positive correlation of 69%. However, none of the clinical parameters studied - age, body mass index, neck circumference and Epworth index - was a good predictor of examination. </p><p><strong>Conclusion:</strong> Clinical diagnosis of the syndrome is more important than an isolated assessment of any factor.</p>
