TaggedAPTARAPThis is the ﬁrst prospective cohort study on AT that sepa-
rately reports the proportion of insertional and midportion AT
as well as their risk factors. The incidence of AT in our study
was 4.2% during a mean follow-up of 20 weeks. The propor-
tion of insertional and midportion AT was 28% and 64%,
respectively, and 8% had a combined type of insertional and
