NFES-CPW, Novel food exchange system for Chinese pregnant women; EER, estimated energy requirement; EAR, estimated average requirement; RNI, recommended nutrient intake; AI, adequate intake; RAE, retinol activity equivalents; DFE, dietary folate equivalent

Below EER/EAR: The number and percentage of derived recipes with energy or nutrient intakes below the EER or EAR value

Above RNI/AI: The number and percentage of derived recipes with nutrient intakes above the RNI or AI value

P-values were assessed using the Wilcoxon rank sum test for non-normally distributed continuous variables or χ² test for categorical variables; nsP > 0.05, non-significant; *P < 0.05, significant; **P < 0.01, significant
