If associated with 1 of these known contributors, RLS is considered to be secondary to the condition. Considering that the prevalence of diseases that are related to RLS could be elevated in the elderly population, it may be the case that the secondary RLS prevalence is also increased. A general increase in secondary RLS and decrease in the migraine prevalence within the elderly population could induce the observed lack of an association between migraine and RLS. We did not attempt to evaluate other medical conditions which were related to secondary RLS in the present study. As such, the results of this study have a limitation regarding secondary RLS.","tracks":[{"project":"TEST0","denotations":[{"id":"26272681-234-240-1506070","span":{"begin":234,"end":236},"obj":"[\"17566118\"]"}],"attributes":[{"subj":"26272681-234-240-1506070","pred":"source","obj":"TEST0"}]},{"project":"2_test","denotations":[{"id":"26272681-17566118-60560363","span":{"begin":234,"end":236},"obj":"17566118"}],"attributes":[{"subj":"26272681-17566118-60560363","pred":"source","obj":"2_test"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"TEST0","color":"#ecab93","default":true},{"id":"2_test","color":"#9395ec"}]}]}}
