Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Used computer‐generated random numbers
Allocation concealment (selection bias)	Unclear risk	Used sealed envelopes but no mention of whether they were opaque and serially numbered
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Lack of blinding may have affected institution of co‐intervention
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Even though not blinded, outcomes such as seizure activity determination is unlikely to be subject to bias in detection
