TLDR
Results reinforce the usefulness of a brief, easy to administer, patient-based index of asthma control.Abstract:
Background Asthma guidelines indicate that the goal of treatment should be optimum asthma control In a busy clinic practice with limited time and resources, there is need for a simple method for assessing asthma control with or without lung function testing Objectives The objective of this article was to describe the development of the Asthma Control Test (ACT), a patient-based tool for identifying patients with poorly controlled asthma Methods A 22-item survey was administered to 471 patients with asthma in the offices of asthma specialists The specialist's rating of asthma control after spirometry was also collected Stepwise regression methods were used to select a subset of items that showed the greatest discriminant validity in relation to the specialist's rating of asthma control Internal consistency reliability was computed, and discriminant validity tests were conducted for ACT scale scores The performance of ACT was investigated by using logistic regression methods and receiver operating characteristic analyses Results Five items were selected from regression analyses The internal consistency reliability of the 5-item ACT scale was 084 ACT scale scores discriminated between groups of patients differing in the specialist's rating of asthma control (F = 345, P P 1 (F = 43, P = 0052) As a screening tool, the overall agreement between ACT and the specialist's rating ranged from 71% to 78% depending on the cut points used, and the area under the receiver operating characteristic curve was 077 Conclusion Results reinforce the usefulness of a brief, easy to administer, patient-based index of asthma controlread more

TL;DR: Black children with asthma have fewer visits with their providers and are less likely to have a written asthma treatment plan than white children, and Asthma providers could focus on improving these specific family-provider interactions in minority children.

Asthma insights from Jordan: cross-sectional observational study
TL;DR: Most of the recruited patients have not achieved optimal asthma control and was associated with low quality of life, highlighting that even in low-income countries, a simple assessment tool such as the ACT can be utilized to screen and categorize asthma control.

TL;DR: If further studies confirm the NET-lowering effect of ICS in the circulation, it can be utilized in diseases where NETosis contributes to the pathogenesis.

The meaning and use of the area under a receiver operating characteristic (ROC) curve.
TL;DR: A representation and interpretation of the area under a receiver operating characteristic (ROC) curve obtained by the "rating" method, or by mathematical predictions based on patient characteristics, is presented and it is shown that in such a setting the area represents the probability that a randomly chosen diseased subject is (correctly) rated or ranked with greater suspicion than a random chosen non-diseased subject.

A method of comparing the areas under receiver operating characteristic curves derived from the same cases.
TL;DR: This paper refines the statistical comparison of the areas under two ROC curves derived from the same set of patients by taking into account the correlation between the areas that is induced by the paired nature of the data.

TL;DR: This model proposes a taxonomy or classification scheme for different measures of health outcome, dividing these outcomes into five levels: biological and physiological factors, symptoms, functioning, general health perceptions, and overall quality of life.
