Comparative analysis of the differences in median (IQR) for HSR and nutrient content between health food (HF) snack products sold in supermarkets and specialty HF stores compared to equivalent products sold in regular aisles (RA) of supermarkets. Differences in median (IQR) nutrient values were assessed via Mann-Whitney U tests.
