LSD = least significant differences; O/OCC_all = orbit/occipital ratio for all patients with TAO; O/T_all = orbit/temporoparietal ratio for all patients with TAO; O/OCC_act = orbit/occipital ratio for all patients with active TAO; O/T_act = orbit/temporoparietal ratio for all patients with active TAO; O/OCC_inact = orbit/occipital ratio for all patients with inactive TAO; O/T_inact = orbit/occipital ratio for all patients with inactive TAO; O/OCC_contr = orbit/occipital ratio for all control patients; O/T_contr = orbit/temporoparietal ratio for all control patients.
Means with 95% LSD intervals show mean ± SEM, SD, and lower limit (LL) and upper limit (UL) of 95% LSD intervals of various groups of tracer ratios.
