Article Title: Effect of device and expiratory maneuver technique on peak expiratory flow measurements
doi: 10.1111/cpf.70067
Figure Lengend Snippet: Estimated marginal means of peak expiratory flow (PEF) by device and expiratory maneuver technique derived from the linear mixed‐effects model with device and technique as fixed effects and subject as a random effect. Points represent mean PEF and error bars indicate 95% confidence intervals.
Article Snippet: Each subject performed three measurements using two expiratory maneuvers (a short, explosive PEF maneuver and a long, spirometry‐style maneuver) with four different devices: the handheld microspirometers Medikro Duo M920 (Medikro Oy, Kuopio, Finland) and MIR Spirobank II Smart (Medical International Research S.p.A., Rome, Italy), the laboratory spirometer Vyntus Pneumo (Jaeger Medical GmbH, Höchberg, Germany), and the Mini‐Wright PEF meter (Clement Clarke International Ltd., Mountain Ash, Wales, UK).
