title: An evaluation of the agreement between three peak flow meters: Wright's, Miniwright's, and Pocket, when used in children.
abstract: Three peak flow meters (PFM), Wright's, Miniwright's II (MPFM), and Pocket, were evaluated in 50 children in a pediatric outpatient clinic. It was found that there was close agreement between the Pocket and the MPFM as shown by an intraclass correlation (rho) of 0.95. Less agreement was noted between the MPFM and the Pocket, respectively, with the Wright's. It was also noted that the coefficient of correlation (r) was not a suitable test for agreement in this study. Both the Pocket and the MPFM also read higher than the Wright's. We conclude that children should be monitored using the same type of peak flow meter.
