2. Fig 1
V˙o2 during continuous exercise. t0 is the onset of exercise, t1 is the time taken to reach a steady state or an asymptote, and t6 is the 6-minute test endpoint. The area between line A and the x-axis is V˙o2 at rest, and line B represents the energy demand of the activity being performed. The area above the trajectory line and under line B is the oxygen deficit.

(A) Rate constant significantly lower for women with SLE than controls (*P<.005), (B) Time to steady state significantly longer for women with SLE than for controls (*P<.016). (C) Oxygen deficit significantly higher for women with SLE than for controls (*P<.028). Error bars indicate 1 SD unit.
