Methods	Randomized controlled trial, states random digit table on page 43.
Participants	78 mothers who had spinal anesthesia for cesarean birth and their full‐term infants who were hypothermic (body temperature < 36.5 ºC) post birth.
Interventions	Control group = infants received routine care while under a radiant warmer. KC group = infants were placed skin‐to‐skin between their mother's breasts after the mothers felt comfortable approximately 50 min post‐cesarean birth and covered with blankets. The duration of KC was 30 min. The infant's rectal temperature was taken after 30 min of KC and then every hour until the temperature was back to normal. If the rectal temperature was < 36.5, the infant was placed under a radiant warmer. The researchers did not state how many KC infants had rectal temperatures < 36.5 at the end of the intervention.
Outcomes	The infant's rectal temperature was taken 30 min after KC started or after radiant warmer care. Infant temperature was recorded hourly starting 1 hour until 6 hours post birth and was plotted on a graph. The number and % of infants in each group who reached normal body temperature after 4 hours was listed.
Notes	Study was conducted in Taiwan.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Abstract states "randomized control trial." States random digit table on page 43.
Allocation concealment (selection bias)	Unclear risk	No information provided.
Blinding of participants and personnel (performance bias) All outcomes	High risk	No information provided. Not possible to blind intervention.
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	No information provided.
Incomplete outcome data (attrition bias) All outcomes	Low risk	86 mothers agreed to participate in the study but data were analyzed for only 78 infants. 2 mothers withdrew because they were tired. 4 mothers felt cold and began to shiver. The other 2 mothers exhibited tachypnea. It was not clear which of these mothers were in the KC and control groups.
Selective reporting (reporting bias)	Unclear risk	Data collected on the % of infants in each group who achieved normal body temperature (36.5 ºC.) after 1‐6 hours and plotted on a graph, numerical data provided for only hour 4.
Other bias	High risk	Infants in the KC group weighed significantly more (30.72 + 3.93) than those in the control group (28.08 + 4.28) (P < .01).
