Table 2 Multivariable proportional-hazards models1 for mortality vs. travel time to hospital and vaccine clinics in children under 5 years old, under 1 year old, and 1 to 4 years old: hazard ratios and 95% confidence intervals

From: Geographic access to care is not a determinant of child mortality in a rural Kenyan setting with high health facility density

Age <1 year 1-4 years <5 years
   Travel model HR 95% CI HR 95% CI HR 95% CI
Time to hospital       
   Pedestrian travel (per 60 min) 0.98 (0.95-1.02) 1.02 (0.96-1.08) 0.99 (0.95-1.04)
   Vehicular travel (per 30 min) 0.98 (0.93-1.03) *1.08 (0.99-1.17) 1.02 (0.95-1.08)
Time to vaccine clinics       
   Pedestrian travel (per 15 min) 1.00 (0.98-1.03) *1.02 (0.99-1.05) 1.02 (0.99-1.04)
Vehicular travel (per 15 min) **0.96 (0.93-0.99) 1.02 (0.95-1.08) 0.98 (0.92-1.05)
