Textual narrative synthesis is an approach which arranges studies into more homogenous groups. Lucas et al [26] comment that it has proved useful in synthesising evidence of different types (qualitative, quantitative, economic etc).
It is a little bit different to calculate grams to teaspoons. For this table, it is easier to use the âeasy calculationâ of 4 grams of sugar per tsp. It means that 1 gram of sugar equals to 0.25 or Â¼ of a teaspoon. Remember that you can keep calculating on your own by multiplying the number of grams by 0.25. For example, for 32 grams of sugar you would take 32 x 0.25, which would equal to 8 teaspoons.
If you were to use the easier calculation of rounding a teaspoon of sugar to 4 grams, then you would have had other numbers. For example, 20 teaspoons x 4 grams, would have equal to 80 grams instead of the 84 grams shown in the table. It is almost an extra teaspoon in difference from the correct amount. This might not be a big deal, but it adds up if you think about it.
