Percentage of ATP inhibited in neutrophils and PBMCs when OXPHOS inhibitor sodium azide was added. Calculated as the amount of ATP after the addition of sodium azide as a percentage of ATP before cells are treated. This shows how reliant the cells are on OXPHOS as an energy source. A lower % ATP inhibition shows a lower reliance on OXPHOS. N = 23. There were no significant differences between CFS/ME and healthy control % ATP inhibition for either cell type (Supplementary Information S3).
