Vaidya 2005.

Methods	Randomized controlled trial.
Participants	110 healthy full‐term infants and their mothers.
Interventions	1) SSC group = the naked infant was placed on the mother's naked chest for 10‐15 min within 1 hour of birth. 2) Control group = after immediate newborn care the infants were dressed and given to their mothers or visitors. Both groups were encouraged to initiate breastfeeding.
Outcomes	Exclusive breastfeeding up to 2‐4 and 4‐6 months post birth, started other feedings before 2 months of age.
Notes	Study was done in Kathmandu, Nepal.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	“...some mother‐baby pairs were selected randomly and after taking verbal consent were allowed to have skin‐to‐skin contact.... In the remaining control group, babies after immediate newborn care were dressed as usual”.
Allocation concealment (selection bias)	Unclear risk	There was little information about study methods and the method of randomization was not described clearly.
Blinding of participants and personnel (performance bias) All outcomes	High risk	Blinding was not mentioned, it is likely that all groups were aware of group assignment.
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Not described.
Incomplete outcome data (attrition bias) All outcomes	High risk	It was stated that 110 women were included in the study and 92 were followed up, the reasons for loss to follow‐up were not stated. It was not clear where the numbers of women lost to follow‐up were the same in the control and intervention groups. There was some discrepancy in numbers in different tables; in a table setting out duration of breastfeeding by mode of delivery only 60 women were accounted for.
Selective reporting (reporting bias)	Unclear risk	Assessment from published study report.
Other bias	Unclear risk	The sample was not described and it was not clear whether the 2 groups were balanced in terms of parity, mode of delivery, and other potentially important variables. Very little information about study methods was provided.
