Figure 2. ³¹P MRS (k_PCr) and CPET (o₂ at _L and o₂ at Peak) data at Baseline (before NACRT)) and at 48±5 hours post-NACRT: lines link data-points (closed circles) for individual patients, and open circles show overall mean±SEM. Mean changes (SEM) between baseline and post-NACRT are for k_PCr −0.4(0.1) min⁻¹, p = 0.001; for o₂ at _L −2.4(0.7) ml.kg⁻¹.min⁻¹, p = 0.004; and for o₂ Peak −4.0(1.3) ml.kg⁻¹.min⁻¹, p = 0.011.
