From: The influence of the peripheral cortisol fluctuation on the success rate of adrenal venous sampling

The histograms showed the success rate (left-sided, right-sided and overall) between groups (PCClow, PCCsim and PCChigh) using different SI cutoff value (1.1, 2 and 3). Panel (a) showed SI ≥ 1.1 as cutoff value and no significant difference between groups on both sides. Panel (b) showed SI ≥ 2 as cutoff value and the significant difference between the following groups: PCChigh and PCCsim, PCChigh and PCClow and PCCsim and PCClow for the right AVS success rate; PCChigh and PCCsim and PCChigh and PCClow for the overall AVS success rate. Panel (c) showed SI ≥ 3 as cutoff value and significant difference between the following groups: PCChigh and PCCsim, PCChigh and PCClow and PCCsim and PCClow for the overall AVS success rate; PCChigh and PCCsim and PCChigh and PCClow for the right AVS success rate; PCChigh and PCClow for the left AVS success rate (*p < 0.05). Abbreviation: AVS: adrenal venous sampling; PCClow: lowest peripheral plasma cortisol concentration; PCCsim: peripheral plasma cortisol concentration that acquired simultaneously with adrenal vein; PCChigh: highest peripheral plasma cortisol concentration.
