Fig. 2From: A specific objective supplemental factor in evaluating acute mountain sickness: ΔHR in combination with SaO2 Effect of △HR cutoff (a) or SaO2 cutoff (b) on the AMS incidence. Comparison of AMS incidence between over and below cutoff values of △HR (a) or SaO2 (b) in AEG and PAG; a: P < 0.01 compared with total AMS; b: P < 0.01 compared with severe AMS; c: P < 0.01 compared with mild AMSBack to article page
