Correction to: Higher bone mineral density at six years of age in very preterm-born infants fed human milk compared to formula feeding. A secondary analysis of an RCT (European Journal of Pediatrics, (2025), 184, 2, (160), 10.1007/s00431-024-05935-3)

In the originally published article entitled “Higher bone mineral density at six years of age in very preterm-born infants fed human milk compared to formula feeding. A secondary analysis of an RCT”, Table 1 is very unregular and is difficult to read, unfortunately. Table 1 Baseline characteristics (Table presented.)
