Treatment effectiveness for comorbid anorexia nervosa and obsessive-compulsive disorder: a systematic review.
Synthesis in International journal of psychiatry in clinical practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveAnorexia nervosa (AN) and obsessive-compulsive disorder (OCD) are severe, commonly co-occurring disorders. AN and OCD comorbidity is associated with worsened prognosis and treatment responses, so better understanding treatment efficacy across both disorders could improve outcomes. We conducted the first known systematic review of non-pharmacological treatment efficacy for comorbid AN and OCD.
methodsA systematic review of PubMed, PsycNet, Scopus, ProQuest and Google Scholar, up to and including January 2024, yielded 14 studies. PRISMA methodology was used. The study was preregistered (PROSPERO CRD42024507762).
resultsAN symptoms tended to improve while OCD symptoms did not. Most studies looked at treatments developed for AN. Studies examined a range of treatment types (e.g., deep brain stimulation and family-based therapy), study types (e.g., case study, single-arm and randomised controlled trial) and spanned all levels of care. Participants were mostly patients with AN, and many also had OCD symptoms. Risk-of-bias was variable.
conclusionCurrent treatments may be effective for AN but not for comorbid OCD symptoms. More research is needed examining comorbid AN and OCD treatment, particularly with more severe OCD. Future efforts should investigate transdiagnostic treatments, utilisation of OCD treatments for AN and longitudinal designs to examine relapse in addition to remission.
