26 February 2018	New citation required and conclusions have changed	We made changes to the main conclusions of the original review.
26 February 2018	New search has been performed	We updated the search for eligible studies to February 2018. We found one randomised controlled trial (two publications) that was eligible for inclusion in this review (Armanian 2014). We included body mass index and measures of body composition in the growth parameters of the primary outcome. We also included new secondary outcome measures: long‐term measures of cardio‐metabolic health (such as insulin resistance, obesity, diabetes, and hypertension). These outcomes were aligned with those of the Cochrane Review titled "Multi‐nutrient fortification of human milk for preterm infants" (Brown 2016). We applied the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to assess the quality of evidence.
