Mantel-Haenzel Hazard ratio computed by comparing each IVM treated group to its corresponding control, thus factoring in each age group’s control mortality. Error bars represent the 95 % confidence interval of the hazard ratio. Each age group showed significantly different hazard ratios as there was no crossover between 95 % CIs. 2DPE: HR = 5.47, 95 % CI = 4.20 – 7.14; 6DPE: HR = 27.89, 95 % CI = 19.84 – 39.02; 14DPE: HR = 11.49, 95 % CI = 7.54 – 17.52Back to article page
