Score differences are presented as mean (SEM). Patients: number of patients per treatment group (OT+/OT– or UT+/UT–). OT+, overtreated in a specific period; OT–, not overtreated in that period; UT+, undertreated in a specific period; UT–, not undertreated in a that period.

^*Bold p values: significant score difference between OT+/OT– and UT+/UT– groups.
