Differences in METs during work-time across occupational categories of the ISCO-88.

<p>CI, confidence interval; ISCO-88, International Standard Classification of Occupations 1988; METs, metabolic equivalents. Intergroup comparisons (low-intensity vs. moderate-intensity vs. high-intensity group) revealed highly significant differences (p<0.001).</p

Comparison of objective SWMA activity data with subjective IPAQ activity data.

<p>HPA_Recreation_IPAQ / HPA_Work_IPAQ, physical activity duration at high intensity (8 METs) based on the International Physical Activity Questionnaire; HPA_Recreation_SWMA / HPA_Work_SWMA, physical activity duration at high intensity (6–9 METs) measured by the SenseWear Mini armband; MPA_Recreation_IPAQ / MPA_Work_IPAQ, physical activity duration at moderate intensity (3–6 METs) based on the International Physical Activity Questionnaire; MPA_Recreation_SWMA / MPA_Work_SWMA, physical activity duration at moderate intensity (3–6 METs) measured by the SenseWear Mini armband. * Intergroup comparisons (low-intensity vs. moderate-intensity vs. high-intensity group) revealed highly significant differences (p<0.001).</p

Bland-Altman plot illustrating the difference in AHI as measured from ApneaLink^TM autoscore versus PSG.

<p><b>Plots present differences between the two methods compared to mean AHI of the two methods. The black solid line represents the mean difference, the black thin lines the 95% confidence intervals on the limits of agreement.</b> ALA, ApneaLink^TM autoscore; PSG, polysomnography.</p

Distribution of patients with and without an OI across AHI categories based on manually revised ApneaLink^TM score.
