Table 3 Selected variables and OR of acute mountain sickness determined by stepwise logistic regression analysis

From: A specific objective supplemental factor in evaluating acute mountain sickness: ΔHR in combination with SaO2

Selected variables P-value OR (95 % CI)
AEG
HR (>25 vs ≤17) <0.01 1.86 (1.24-2.79)
SaO2 (<88 % vs >90 %) <0.01 1.72 (1.24-2.38)
HR (>87 vs >82) 0.08 1.38 (0.97-1.97)
PAG
HR (>15 vs ≤7) <0.01 2.39 (1.34-4.26)
SaO2 (<86 % vs 86 %-88 %) 0.06 1.86 (0.98-3.57)
SaO2 (<86 % vs >88 %) 0.03 2.86 (1.39-5.89)
