Shaw 1999.

Methods	Single‐centre RCT. 12 month follow‐up. Conducted in UK.
Participants	101 otherwise healthy babies with clefts of lip, palate, lip and palate. Age: randomised at birth. Gender (m/f): Gp1 = 27/22, Gp2 = 31/21. Isolated cleft lip: Gp1 = 10, Gp2 = 15. Isolated cleft palate: Gp1 = 16, Gp2 = 15. Cleft lip and palate: Gp1 = 23, Gp2 = 22. South Asian mother: Gp1 = 4, Gp2 = 12.
Interventions	Gp1. Squeezable bottle with Nuk orthodontic teat (n = 49). Gp2. Rigid bottle with Nuk orthodontic teat (n = 52). All mother‐infant pairs received individual assessment of infant's oral feeding.
Outcomes	Weight (kg), head circumference (cm) and crown‐heel length (cm) were measured by trained researcher at birth, 6, 13, 26 and 52 weeks. Parental satisfaction was recorded as mothers report of ease/pleasure of feeding. 24 hour log of time taken to feed. Reliability of feeding methods (number of adjustments necessary).
Notes	Funded by Action Research Grant and North West Regional Health Authority, UK.

Bias	Authors' judgement	Support for judgement
Adequate sequence generation?	Low risk	Generated by trial statistician.
Allocation concealment?	Low risk	Opaque envelopes opened by clinician.
Blinding? All outcomes	High risk	Outcome assessor was trial investigator.
Incomplete outcome data addressed? All outcomes	Low risk	Drop outs listed and described in full.
Free of selective reporting?	Low risk	Length, height and head circumference measures listed.
Free of other bias?	Low risk	Comparable baseline data. Adequate follow‐up period.
