Differences between numbers of apneas and hypopnoeas (Panel a), apneas (Panel b) and hypopneas (Panel c) estimated by NOWAPI® and by respiratory polygraphy are presented for each of the common 15-min periods (n = 452) of the recording night. The x-axis plots the difference [NOWAPI® minus Respiratory Polygraph] and the y-axis the number of records. Panel d presents the Apnea-Hypopnea Index (events per hour) by patient for the overall recording night, estimated by NOWAPI® plotted against polygraphy with a 1:1 fit line. PP data set with detailed NOWAPI® data files indicating correct connection (n = 14)
