Figure 2. Non-inferiority assessment of vaccine response to poliovirus types 1, 2, and 3, four weeks after booster vaccination.

Figure 2.

Differences in vaccine response are presented along with 90% confidence intervals around the estimated difference. The hashed line represents the non-inferiority margin defined at −12.5%. Non-inferiority is concluded if the lower bound of the 90% confidence interval falls to the right of the non-inferiority margin. (2A) IPV at 14 weeks and fIPV booster (Arm B) in comparison with IPV at 14 weeks and IPV booster (Arm A). (2B) IPV at 6 weeks and fIPV booster (Arm C) in comparison with IPV at 14 weeks and fIPV booster (Arm B).
