aAnticholinergics used were either ipratropium bromide or atropine delivered via aerosol. Results reviewed in detail elsewhere [35]. Abbreviations: PC20 and PD35: provocative concentration (or dose) of agonist producing a 20% or 35% decrease, respectively, in forced expiratory volume in 1 sec (FEV1); PC100 SRaw: provocative concentration of agonist producing a 100% increase in specific airways resistance. |
