Study characteristics
Methods	Randomised controlled trial, Argentina
Participants	74 hospital paediatric resident physicians. " A total of 81% were female; the mean age was 27.3 ± 1.4 years; 57% were working in inpatient areas, 35% in the outpatient clinic, and 8% in the intensive care unit." " A comparison of the characteristics of both groups (experimental and control) revealed no significant differences." (p. 494)
Interventions	1) Experimental: self‐care workshop intervention (n = 37). quote: "The experimental group received a brief intervention consisting of two 2.5‐hour workshops directed by mental health professionals, which covered repercussions of burnout syndrome on professional activity, recognition of risk indicators for burnout syndrome, and tools to cope (identification of strengths, coping behaviors, preventive and self‐care behaviors)." (p. 494) 2) Control: (n = 37) No intervention
Outcomes	MBI
Identification
Notes	It is unclear why 43 (37%) out of the available 117 resident physicians did not participate in the study. Not able to include in analysis due to missing data.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	"After administration of the questionnaire, subjects were randomly assigned to one of the two study groups." (p. 494)
Allocation concealment (selection bias)	Unclear risk	Not reported.
Blinding of participants and personnel (performance bias) All outcomes	High risk	Participants not blinded.
Blinding of outcome assessment (detection bias) All outcomes	High risk	Participants were not blinded whereas outcomes are self‐reported.
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Apparently no participants were lost to follow‐up
Selective reporting (reporting bias)	Unclear risk	The authors do not report standard deviations with the mean MBI subscale scores.
Other bias	Unclear risk	It is unclear if these 74 were all the participants or only those that could be followed up.
