Participants	Inclusion criteria: n.r. Exclusion criteria: n.r. Mean/median age (range), years: n.r. Gender: n.r. Tumour/cancer type: n.r. Chemotherapy regimen: cisplatin Country: n.r.
Interventions	Experimental: arm A: granisetron granisetron + dexamethasone (8 mg i.v., then treatment 4 mg t.d.s. for 3 days afterwards) Experimental: arm B: ondansetron ondansetron + dexamethasone (8 mg i.v., then treatment 4 mg t.d.s. for 3 days afterwards)
Outcomes	not reported
Notes	poster presentation
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Comment: randomised study but method of randomisation not described
Allocation concealment (selection bias)	Unclear risk	Comment: allocation concealment not reported
Blinding of participants and personnel (performance bias) Blinding of participants	Low risk	Comment: double‐blind
Blinding of participants and personnel (performance bias) Blinding of personnel	Low risk	Comment: double‐blind
Blinding of outcome assessment (detection bias) Subjective outcomes (Patient reported outcomes)	Low risk	Comment: both patients and personnel were blinded towards the intervention and thus had no influence on outcome assessment
Incomplete outcome data (attrition bias) Subjective outcomes (Patient reported outcomes)	Unclear risk	Comment: not reported
Selective reporting (reporting bias)	Unclear risk	Comment: not evaluable, conference abstract only
Other bias	Unclear risk	Conference abstract, not evaluable
