Individual and mean ( SD) data for rostrolateral medulla (RLM) and non-RIM groups. Anthropometric data: body mass index (BMI). Lung function data: the ratio of forced expired volume in 1 second to forced vital capacity (FEV1/FVC), vital capacity (VC). Chemosensitivity: ventilatory sensitivity to inhaled CO2, the slope of the response curve derived from the ventilation plotted against CO2 (ΔV˙/ΔCO2). Exercise data: the slope of the response curve derived from the change in ventilation plotted against the change in oxygen uptake (ΔV˙/ΔV˙O2). For one patient (LB) no exercise data were available (see text).
