Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk No detail
Allocation concealment (selection bias) Unclear risk No detail
Blinding of participants and personnel (performance bias) 
 All outcomes High risk Therapists and participants cannot be blinded in trials of family‐based therapy
Blinding of outcome assessment (detection bias) 
 All outcomes Unclear risk No detail
Incomplete outcome data (attrition bias) 
 All outcomes High risk
  1. There is not a full description of why people left the intervention in each group

  2. There are 3 hospitalisations but it is unclear from which groups

  3. No ITT analysis

  4. For the main outcome they do compare ITT to completer analysis.

Selective reporting (reporting bias) High risk
  1. Do not report outcomes from the Eating Conflict subscale of the IBC

  2. Authors report that they collected data on both general and family functioning, but the data are not reported in a format that is useable for analysis

Other bias High risk
  1. Small sample size

  2. Baseline imbalance ‐ for subtype of AN

  3. Inaccurate, with conflict in reporting (state 60% in "good" category but then report N = 7 in each group for "good", which is less than 60%)
