Patient or population: preterm (< 37 weeks) and low birth weight (< 2500 g) infants
Settings: high‐income countries, and low‐ and middle‐income countries
Intervention: topical oil Comparison: another topical oil | ||||||

| *The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI: confidence interval; RR: risk ratio. | ||||||
aDowngraded one level due to serious risk of bias (caregivers and investigators not masked). bDowngraded two levels due to serious imprecision. There were no events in either arm.
