Figure 1. Timeline of the four study visits in the clinical pathway.

Figure 1

At visit 1, the patients received an HSAT to conduct a validated 2-night test at home to assess baseline measurements. At visit 2, the results were analyzed and discussed with the patients. If POSA was confirmed, the patients received an SPT for a trial period of 28 days. At visit 3, the patients received the same HSAT to perform a 2-night sleep test with the SPT, during the last week of the SPT-trial. At visit 4, the results were discussed and compared to the results of the baseline HSAT. HSAT = home sleep apnea test, POSA = positional obstructive sleep apnea, SPT = sleep position trainer.
