IQR, Interquartile range.
a
Forced sex had very low prevalence and was not used to estimate the latent class analysis model. Table shows the prevalence of forced sex among people classified into each class according to responses on the remaining symptoms.
b
Prevalence based on classification by posterior probability of class membership.
