Fundamentals of parenteral nutrition in emergency pediatrics

All the main recommendations in this handbook have their own gradation, which is measured by the level of evidence and recommendations, denoted in Latin letters from A to D. Each gradation corresponds to a certain level of data evidence. This means that the recommendations were based on research data, which have varying degrees of certainty. The higher the rating of a recommendation, the higher the credibility of the studies on which it is based. Below is a scale that describes the different levels of gradation for the recommendations included in this handbook.
