Input: Three eligible trials were identified. Two trials, including one trial with a much larger sample size than the others combined, were from geographical areas with low population selenium concentrations. Meta-analysis of the pooled data showed a significant reduction in the proportion of infants having one or more episodes of sepsis associated with selenium supplementation [summary RR 0.73 (0.57 to 0.93); RD -0.10 (-0.17 to -0.02); NNT 10 (5.9 to 50)]. Supplementation with selenium was not associated with improved survival, a reduction in neonatal chronic lung disease or retinopathy of prematurity. Supplementing very preterm infants with selenium is associated with benefit in terms of a reduction in one or more episodes of sepsis. Supplementation was not associated with improved survival, a reduction in neonatal chronic lung disease or retinopathy of prematurity. Supplemental doses of selenium for infants on parenteral nutrition higher than those currently recommended may be beneficial. The data are dominated by one large trial from a country with low selenium concentrations and may not be readily translated to other populations.
Output:

The review of trials of selenium supplementation for preterm babies found that it reduces sepsis (blood infection). It has not been shown to reduce other complications or increase survival. No adverse effects were reported. Higher than usual levels of selenium supplementation may be beneficial, but more research is needed as most of the evidence comes from a country where selenium levels were unusually low.
