    Cardiopulmonary and metabolic responses during a 2-day CPET in [ME/CFS]: translating reduced oxygen consumption [...], Keller et al, 2024

    I've tried to use JASP, the statistical program Keller et al. used and it gave the same result as the method explained in the quote above. If I calculate the mean and std I get the same results as in the paper so I don't think I've made an error in data extraction. Anyone who can explain the...

    Cardiopulmonary and metabolic responses during a 2-day CPET in [ME/CFS]: translating reduced oxygen consumption [...], Keller et al, 2024

    Interesting graphs @forestglip, the red ME/CFS dots seem scattered around the blue HC ones without a clear pattern. Has anyone been able to replicate their calculation of effect sizes? For example for VO2 (ml.kg−1.min−1) at maximal exercise, they report mean values for the ME/CFS group of 20.8...

    Cardiopulmonary and metabolic responses during a 2-day CPET in [ME/CFS]: translating reduced oxygen consumption [...], Keller et al, 2024

    Already had a quick peak and it seems that there is quite a lot of overlap between the two groups if you plot the difference between day 1 an day 2. Here's for example the workload at the ventilatory threshold for the total sample, which in the past showed the biggest differences. (EDIT: The...
