Table 4 The most commonly stated prescribed amounts for the different therapies. Therapy notations follow Table 1, whereas prescription alternatives 1–6 refer to Table 2. The prescribed amounts are given either as median, 10th and 90th percentiles, or as median, minimum, and maximum, depending on the replies obtained. The percentiles are used to better accommodate some occasional outlier values
