Methods	RCT Generation of allocation sequence: randomly assigned using sealed envelopes Allocation concealment: sealed envelopes Blinding: none Inclusion of participants in analysis: > 90% Duration: not specified; only stated that trial was done for 10 consecutive months
Participants	Number of participants: 93 enrolled Inclusion criteria: males; age 3 months to 5 years; watery diarrhoea < 5 days; presence of dehydration; weight for height > 70% of 50th centile of reference standard Exclusion criteria: female; persistent vomiting; bloody diarrhoea; temperature > 39°C; other associated medical illness; intake of antibiotics during illness
Interventions	Glucose ORS: 33 participants. Pop rice ORS: 31 participants. Mung bean ORS: 29 participants.
Outcomes	Total stool output in first 24 hours. Total stool output from randomization to discharge. Duration of diarrhoea. Number of participants with unscheduled use of intravenous fluid. Number of participants with vomiting.
Glucose‐based ORS osmolarity	≥ 310 mOsm/L
Setting	Hospital‐based trial Location: New Delhi, India
Notes	Participants who were given glucose ORS were more malnourished as compared to the treatment groups, but the difference was not statistically significant
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	RCT: randomly assigned using sealed envelopes
Allocation concealment (selection bias)	Unclear risk	Sealed envelopes
Blinding of participants and personnel (performance bias) All outcomes	High risk	Participants, providers, and outcome assessors were not blinded
Blinding of outcome assessment (detection bias) All outcomes	High risk	Participants, providers, and outcome assessors were not blinded
Incomplete outcome data (attrition bias) All outcomes	Low risk	The trial included all randomized participants in the analysis
Selective reporting (reporting bias)	Low risk	The trial reported over 90% of the included participants in the final analysis
Other bias	Unclear risk	We did not detect any other sources of bias
