Relative accuracy. Data for hMPV-A1 (A) and hMPV-B1 (B) show log2 of the expected GMT on the x-axis and log2 of the observed GMT on the y-axis. Relative accuracy was evaluated by calculating the percentage of recovery on the GMT of the observed values and the expected (true) titers obtained by applying the following formula: 100*(observed GMT/expected GMT). Dashed red lines represent 50% and 200% recovery of the expected titer. GMT: geometric mean titer; NT: neutralizing titer.
