In Table 1 of the above-mentioned article [Reference Castle and Maza1] the units for ‘Vaccine composition’ (column 1, line 5) are incorrect. They should be µg, rather than mg.
In Figure 1, the orange bar for ‘ATP all cervical precancer’ should indicate 42·7%. In the caption for Figure 1, reference [29] should be [27]. The correct version of Figure 1 and caption are given below.
A comparison of vaccine efficacy against targeted HPV type-related (purple bars) and all cervical precancer (CIN2, CIN3, or AIS) (orange bars) by 2vHPV [27], and 4vHPV [28], for the HPV-naive populations (TVC-naive and ATP, respectively) and the entire vaccinated cohort (TVC and ITT, respectively). TVC, Total vaccine cohort; ATP, attention to protocol; ITT, intention to treat.
