Conditions here are listed
according to
lifetime risk, which is the likelihood of
having a condition during your entire lifetime.
The availability of accurate data regarding lifetime risks
is much lower, compared to prevalence or incidence rates,
so much of the information below is likely to be dubious.
In most cases, the rates refer to the USA
or other industrialized nations.
