Results: Main clinical, analytical and polygraphic data: 58.1±6.4 years, body mass index 32.4±5.4 kg/m2, 70.4% female, HbA1c 8.0±1.9%, AIH 27.4 events/hour (in the range of severe sleep apnea and hypoapnea index), and CT90% 32.9%. Nocturnal concentration of urine total metanephrines were higher than diurnal levels (226±12 vs 98±13 μg/l; P=0.085). In addition, its nocturnal concentration was significantly associated, in a positi...
