CPD stands out from other research methods because it vividly illustrates how independent and dependent variables may shift between ...
Nutritional information for these recalls are best analysed using computer-based nutritional assessment programs. [ 1 ] A 2013 study determined that the 24-hour multiple-pass recall is a sufficient method for assessing dietary intake of toddlers of Iraqi or Somali born mothers in Norway.
