The data presented in this report are weighted estimates, generated using SAS 9.4. Estimates are not reported where specific categories include less than 30 individuals (unweighted), except where noted as not meeting Statistics Canada’s quality standards. The CTNS/CTADS/CTUMS survey weights assigned by Statistics Canada in the annual datasets were used for CTNS/CTADS/CTUMS analyses, and the CSTADS/YSS survey weights were used for CSTADS/YSS analyses. CTNS/CTADS/CTUMS and CSTADS/YSS were not analysed together and there was no overlap of the survey weights between the two surveys.
Statistical comparisons between groups/years were tested using weighted regression analyses in SAS 9.4. Bootstrap weights were used to perform significance testing where available. Where statistical testing has been performed, comparisons are marked with a superscript number, which refers to a p-value that can be found in the Index of Statistical Tests. Throughout the report, the term “significant” has been reserved for instances where statistical testing has been performed, with p See Significance testing for further details.
