Methods	Six‐month, systematic, simple randomised trial of children referred to a child neurology clinic (the author was from Guilan University of Medical Sciences, Iran, so it was likely that the study was also conducted there) 2‐arm trial: CBZ and PB
Participants	Children aged 2 to 12 years with partial seizures with secondary generalisation Number randomised: CBZ = 36, PB = 35 36 male children (53%) 100% partial seizures, the per cent newly diagnosed was not stated Age range: 2 to 12 years Study duration: 6 months Mean follow‐up: not stated
Interventions	Monotherapy with PB or CBZ. Doses started or achieved not stated
Outcomes	Proportion seizure‐free Response rate and rate of side‐effects Seizure frequency and seizure duration
Notes	The trial was reported in abstract form only with very limited information. Outcomes chosen for this review were not reported; IPD were not available.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	The trial was described as a 'systematic simple randomised study'; no further information was provided.
Allocation concealment (selection bias)	Unclear risk	No information was provided.
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	No information was provided on blinding.
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	No information was provided on blinding.
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	No attrition rates were reported; it was unclear if all participants were analysed.
Selective reporting (reporting bias)	Unclear risk	There was no protocol available; the study was available in abstract format only. Outcomes for this review were not available.
