Factor Hazard Ratio (95%CI) Significance
Trial 1
 Treatment (mite) 1.87 (1.33 – 2.62) p < 0.001
 Brood care 38.7 (10.3 – 145.4) p < 0.001
 Comb building 84.5 (4.04 – 1770) p = 0.004
 Resting 4.0 (0.84 – 18.7) p = 0.082
 Ventilation 11.5 (1.02 – 130.6) p = 0.048
 Grooming 4.9 (1.20 – 20.1) p = 0.027
 Foraging 0.001 (0.000 – 0.56) p = 0.032
Trial 2
