Figure 6

Left: patient-level dose response data by baseline FEV 1 category (quartiles) with LOESS curves through the data; Right: zoom-in on smooth curves represented in a three-dimensional manner, after subtracting the placebo effect, to highlight dependency of the response on dose and baseline FEV 1 (note: the mid-value of the intervals is taken for each baseline FEV 1 category in the right-hand plot).
