Number of systematic reviews included 199
Summary of Findings From 199 included reviews of observational studies randomly selected from those indexed in EMBASE, MEDLINE, and Epistemonikos in 2019. 56.8% had causal intent. Systematic reviews with causal intent were more likely to investigate therapeutic clinical intervention (33.6% vs. 12.8%). Although 78.8% of those with causal intent used causal language in one or more sections of the title, abstract, or main text, only 4.4% consistently used causal language throughout the manuscript, and 21.2% did not use causal language at all.
