  1. Mean scores refer to observed cases
  2. All subscores favour the TAU condition, with the exception of the BSI Hostility score (only OC) at 18 weeks and O 45 severity at 12 weeks (only LOCF); scores favouring FB are indicated in italics, data in bold are significant scores
  3. Multilevel analyses, taking into account the levels of the patient, therapist and time, showed time by treatment interactions in ORS, BSI and OQ45 (from start to T6, T12,T18,T24)
