Table 3. The results of multiple binary logistic regression for the individual predictors of AMS in Nepalese pilgrims upon arrival to Gosainkunda (4380 m).

Variable†	B (SE)	Odds ratio		p-value
		Statistic	95% CI
Constant	−1.57 (0.19)	0.60		0.003
Sex	0.57 (0.23)	1.77*	1.14, 2.75	0.011
Age	1.06 (0.22)	2.89*	1.89, 4.39	<0.001
Ascent rate	0.81 (0.17)	2.26*	1.35, 3.76	0.002

^†Males, subjects ≤35 years, and the 2-day ascent group were used as the reference categories for the calculation of odds ratios.

^*This result is significant (i.e., p<0.05).
