This was my standout observation from this valuable study.
Post-hoc comparison of cortisol concentrations revealed that Long COVID participants had approximately 50% lower circulating levels (median levels 47.01 ng/mL LC vs. 90.32 ng/mL HC vs. 82.67 ng/mL). Evaluation of paired ACTH levels revealed no significant differences across groups.
