Derivation and Validation of a Combination of BOSTON Score and DES-OSA Score for Selection of OSA Patients.
Derivation and Validation of a Combination of BOSTON Score and DES-OSA Score for Selection of OSA Patients.
Derivation and Validation of a combination of BOSTON score and DES-OSA score to exclude OSA
 or to confirm OSA in patients.
The aim of this study is to derive and to validate a combination of BOSTON score and DES-OSA
 score.

 Firstly, the investigators will use a retrospective cohort of 400 patients to determine this
 combination. It will allow classifying patients in 3 groups: 1) patients for whom OSA can be
 excluded with certitude, 2) patients for whom OSA can be diagnosed with certitude, and 3) an
 intermediate group.

 Secondly, the 100 patients included in this study will serve to validate the cutoff of the
 abovementioned combination into a new population.
Inclusion Criteria:
