Mean FEV₁ and mean FVC changes following regadenoson.

Notes: For comparison of regadenoson and placebo for all time points, data are expressed as least squares mean ± standard error (P≥0.074 and P>0.28, respectively). The regadenoson curve is staggered slightly to the right to improve visualization of both sets of error bars.
