Another study that compared MiniWright®, Assess®, Pulmo-graph® and Wright Pocket® meters with PEF values recorded during the forced vital capacity maneuver of patients with asthma, chronic obstructive pulmonary disease (COPD) and bronchiolitis, as well as healthy subjects, also found that the Assess® meter provided a highly significant difference. 8 These studies observed results that are equivalent in some aspects to those of the present study.
