Acceptable Limits Of Agreement

In the context of contract analysis, we need to start from a constant convergence across the whole range of measures. In some of Figures 1 and 2, the validity of this hypothesis is questionable, as in some plots variability appears to increase with the average respiratory rate. This could be due to a soil effect that is unlikely to have a respiratory rate below a certain threshold (e.g. B 10 breaths per minute) and that it is indeed impossible that it is less than zero. As a result, the range in which differences between devices must be located is artificially restricted when the respiratory rate is low; high values, there are no such restrictions. Therefore, the limitations of the method of agreement are most used in situations where the scope of the measure is completely unlimited and where the land effects and ceilings are negligible; However, if there are references to floor or ceiling effects, this should be taken into account when interpreting the parcels and Bland-Altman agreements. Where effects exist on the floor or ceiling, researchers should be aware that an acceptable agreement (at least partially) may be a consequence of the limited range and does not necessarily reflect the ability of different methods/devices to agree. The effects of soils and ceilings can also lead to non-compliance in differences in results. [20] For comparison purposes, the resulting match limits were compared to those obtained from a solid effects approach based on an extension of the ANOVA method presented in the Bland-Altman file[3] in case the “actual value varies”. The extension of the Bland-Altman ANOVA method included the treatment of activities as another “between dentans” factor in the ANOVA process, and then ignoring the specific results of this factor in calculating the boundaries of concordance. It is estimated that approximately 328 million people worldwide live with COPD,[10] including at least 3 million in the United Kingdom,[11] many of whom suffer from worsening the disease that can lead to hospitalization.

Respiratory frequency monitoring devices could be used to detect early changes in respiratory frequency, to detect these exacerbations at an early stage, allowing timely treatment to help slow deterioration and prevent hospitalizations.
