High risk of bias (ROBIS) Limited quality assessment or no risk of bias Insufficient literature searches Single reviewer / lack of double checking Poor consideration of publication bias |
Number of systematic reviews included | 5 |
Summary of Findings | All five included reviews reported significantly increased risk with higher levels of alcohol consumption, but four of the five included reviews had a high risk of bias using ROBIS. One review searched only a single electronic database, one review did not specify literature search terms, three reviews did not specify that at least two reviewers performed study selection and/or data collection and/or risk of bias assessment for all articles, three reviews did not perform a risk of bias or methodological quality assessment, and one review did not address publication bias. Moreover, although sub-group analyses were reported by sex and age there were evidence gaps for many important factors. Finally, Over 70% of systematic reviews and meta-analyses published to March 2022 of all-cause mortality risk associated with alcohol consumption did not exclude former drinkers from the reference group and may therefore be biased. |
