PS: performance status, NCCN: National Comprehensive Cancer Network, NCI PDQ: National Cancer Institute Physicians Data Query, BCCA: British Columbia Cancer Agency, CCO: Cancer Care Ontario, and SIGN: Scottish Intercollegiate Guidelines Network. aLevels of evidence: level I: evidence obtained from a systematic review of all relevant randomised controlled trials; level II: evidence obtained from at least one properly designed randomised controlled trial; level III: evidence obtained from well-designed controlled trials without randomisation (these include trials with “pseudorandomisation” where a flawed randomisation method was used (e.g., alternate allocation of treatments) or comparative studies with either comparative or historical controls); level IV: evidence obtained from case series. Taken from the National Health and Medical Research Council (NHMRC) hierarchy of levels of evidence [33]. |
