Methodology of bronchial responsiveness

Occasional reviews Methodology of bronchial responsiveness

Recommendations for the standardisation of bronchial challenge were made in 1985, and updated in 1993. However, neither document recommended a single protocol or even criteria that would recommend the adoption of a particular method. Even the terminology lacks uniformity, bronchial responsiveness being used in this review in the hope that it oVends the fewest number of readers. Distinction has ...

Measuring bronchial responsiveness in epidemiology.

Bronchial responsiveness in active steelworkers.

Coke-oven workers are exposed to dust and irritant gases. Therefore they are at risk of developing lung diseases including chronic bronchitis. Nonspecific bronchial hyperresponsiveness (BHR) has been advocated as a potential risk factor predisposing to the development of chronic bronchitis. In a previous study, we showed that prevalence of BHR was higher in retired coke-oven workers than in ret...

The significance of bronchial responsiveness in children.

On both the clinical and epidemiological level, there is extensive information about bronchial responsiveness (BR) in childhood [1]. For technical reasons, however, there is little data on infants and pre-school children, although new techniques for measuring changes in imrathoracic airway function have made this feasible, even in the youngest subjects. Exercise tests were first used to provide...

Comparing and combining studies of bronchial responsiveness.

BACKGROUND There is no standardised protocol for the measurement of bronchial responsiveness. Results from different studies are difficult to compare and combine. METHODS Analyses are divided between those of a continuous outcome, which can be directly standardised as effect size, and those based on a binary outcome. A published method is used to convert an odds ratio to equivalent effect siz...
