Dare 2001.

Methods	RCT of 3 forms of therapy vs. routine care for anorexia nervosa
Participants	84 participants with DSM‐IV anorexia nervosa Exclusion criteria: people with severe low weight, severe health consequences or suicidality
Interventions	Intervention 1: 1 year of focal analytic therapy (derived from Malan 1976) (mean 24.9 sessions) Intervention 2: 7 months of cognitive analytic therapy (mean 12.9 sessions) Intervention 3: 1 year of family therapy Control: routine care
Outcomes	Primary outcome measure was body weight measured as body mass index. Morgan‐Russell Assessment Schedule for anorexia nervosa
Notes	Both individual psychotherapies were methods of STPP
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Stratified randomisation method called the 'minimisation method' was used. Method of sequence generation was unclear
Allocation concealment (selection bias)	Low risk	Sealed envelopes were used
Blinding (performance bias and detection bias) All outcomes	High risk	Some ratings were done by unblinded clinicians No psychotherapist was blinded to the treatment delivered Blinding participants to treatment group not possible
Incomplete outcome data (attrition bias) All outcomes	Low risk	ITT analyses were performed. None of the differences between treatments in the rates of engagement was statistically significant
Selective reporting (reporting bias)	Unclear risk	Some measures of the Morgan Russell Schedule were not reported by therapy group, rather for the whole group only. The stated reason for this was that there were no intra‐group differences
Other bias	Unclear risk	Comment: insufficient information to permit judgement
