Boxplot comparison showing the change flux control ratios (FCR) (halothane-exposed control) for each respiratory state. MHN samples (n=36) were plotted with MHS samples (n=23), further split into MHSh (n=12) and MHShc (n=11) subgroups. Boxplots show median, inter-quartile range (IQR) and min-max response range for each phenotype. Comparisons labelled with an asterisk show statistically significant post hoc pairwise comparisons (refer to Table 2 for exact P-values). CI, complex I; CII, complex II; CIV, complex IV; ETS, electron transport system; MHN, malignant hyperthermia-negative; MHS, malignant hyperthermia-susceptible; MHSh, abnormal response in the in vitro contracture test to halothane but not caffeine; MHShc, abnormal response in the in vitro contracture test to halothane and caffeine; OXPHOS, oxidative phosphorylation.
