Methods	Study design: randomized trial Unit of allocation: patient Unit of analysis: patient Power calculation: done
Participants	Care setting: ambulatory care, specialized care, Denmark Health professionals: 49; various types; fully trained Patients: 4349; pediatrics
Interventions	Multifaceted intervention: Patient‐mediated intervention (question prompt list) + other (digital audio recording) Single intervention: other (digital audio recording) Usual care: Quote: "The study was designed as a three‐armed randomised controlled trial. One group of patients received standard care (Control), while the other two groups received either QPL in combination with a recording of their consultation (QPL‐DAR) or only the recording (DAR)." page 244
Outcomes	Involvement in decision making (qualitative)
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	"Patients were randomly assigned on a weekly basis to one of the three groups using computer‐generated random numbers." page 244
Allocation concealment (selection bias)	Unclear risk	Comment: not enough information to make a judgement.
Blinding (performance bias and detection bias) Participant‐reported outcome	High risk	Comment: Quote: "Neither the patients nor the health professionals were blinded to the randomisation group. Blinding would have required recordings of consultations in the control group without the patients having the possibility to replay the consultation, which we found unethical." page 248
Incomplete outcome data (attrition bias) Participant‐reported outcome	High risk	Comment: very high rate of loss to follow‐up and proportion of losses to follow‐up were not well‐balanced between groups (flow chart).
Selective reporting (reporting bias)	Unclear risk	Comment: study protocol not available to permit judgement.
Other bias	Low risk	Comment: no evidence of other risk of biases.
Baseline measurement? Participant‐reported outcome	Unclear risk	Comment: no information.
Protection against contamination?	Unclear risk	Comment: not enough information to make a decision.
Baseline characteristics patients	Low risk	Comment: characteristics between groups were similar at baseline (Table 1).
Baseline characteristics healthcare professionals	Unclear risk	Comment: no information about clinicians at baseline.
