7.3. The tables present data for each injury factor at issue on an annual basis for the period, either in columns or rows. 85 The tables set out yearly industry-wide absolute values, which are in each case redacted from the non-confidential version. Some of the tables contain an additional column or row setting out year-on-year percentage changes in the redacted data throughout the relevant period. 86 Hence percentage changes from 2006 to 2007, from 2007 to 2008 and from interim 2008 to interim 2009 are shown in each such table. The year-on-year percentage changes do not indicate the significance of the changes. That is, an increase of 100%, for instance, may represent an increase from 1 to 2 units, or an increase from 100 to 200 units in any given case. 87
