Declarations

:

: Ethics approval for retrospective chart review and data abstraction was obtained by authors from Research Ethics Boards at each study site: the Hamilton Integrated Research Ethics Board (McMaster University) granted approval in Hamilton (3734) and in Niagara (18–047-C); the Newfoundland and Labrador Health Research Ethics Board non-clinical trial subcommittee (Memorial University) granted approval in St. John’s (2018.167). Need for patient consent was waived by each Research Ethics Board (given retrospective low risk nature of study). Data was irreversibly deidentified before being pooled for analysis. All research was performed in accordance with guidelines and regulations as laid out by respective research boards, and follows standard protocol for retrospective chart reviews with no patient contact and minimal risk.
