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).
