A meta-analysis of 24 observational studies, including a total of 1,644 people, found no significant differences in predictive correlations between the WatchPAT 100 or 200 and polysomnography for apnea-hypopnea index, oxygen saturation, oxygen desaturation index (how often blood oxygen levels drop), respiratory disturbance index (abnormal breathing events per hour), and lowest oxyhemoglobin saturation (lowest point of oxygen desaturation)
These effects were achieved under reduced activation of noncanonical signaling pathways including receptor internalization and -arrestin recruitment, an initially surprising observation as these have previously been linked to increased GLP-1R responses when measured acutely 10,14,36
