Design outcomes

Primary

MeasureTime frame
The main study parameters include patient characteristics, symptoms, clinical presentation and management of anogenital LS in girls.  The primary endpoint is the difference in these parameters between the premenarche group and the postmenarche group. 

Secondary

MeasureTime frame
The secondary study parameters include the persistence of anogenital LS after menarche and the disease course in patients with persistent anogenital LS.Menarcheal status is determined at the time of LS diagnosis. If the age of menarche/menarcheal status is unknown, patients will be categorized based on the average age of menarche in the Netherlands. Patients younger than this age will be classified as premenarcheal, while patients at this age or older will be classified as postmenarcheal. The secondary endpoint is the proportion of girls with persistent anogenital LS after menarche and an overview of the course of disease in these patients with persistent anogenital LS at specific time points (first visit, second visit, first visit after menarche and most recent visit).
