Extended Data Fig. 4: FGF21 dynamics stratified by major clinical symptoms in participants with mitochondrial disease.
From: Mitochondrial and psychosocial stress-related regulation of FGF21 in humans

Two-sided Mann-Whitneyās U-tests comparing (a) baseline (PMāfed, preāstress) serum FGF21 concentrations in MitoD participants who either do (Symptom +) or do not (Symptom ā) carry a given clinical symptom and (b) FGF21 reactivity, expressed as the net percent change from baseline. Bar graphs represent mean FGF21 values. Error bars represent standard error of the mean (SEM).
