Number of participants in the analyses and properties of New Nordic Diet (NND) scores (exposure) and child development outcomes at time of measure, such as number of participants, mean score, standard deviation (SD), and score range. Valid percent of participants in categories of low, medium and high adherence to the NND, and number and percentage of participants in the low score child development group (2SD below the mean)
