Report and Interpretation of Randomized Controlled Trials with Statistically Nonsignificant Results for Primary Outcomes in the Anesthesia Domain: A Systematic Review

Conclusion section in 66 articles. The most common spin location was the Results section, and the type of spin was focused on statistically significant within-group comparisons. The most common spin strategy was language use that implied a benefit.SummarySpin reporting was highly prevalent in RCT reports in the anesthesia domain, and abstracts may effectively reflect the spin reporting status in articles. We scrutinized instances of spin within RCTs that failed to yield statistically significant results; however, the potential existence of spin in studies reporting statistically significant results may also exist. This warrants critical evaluation and consideration, and the application of a fragility index may be indispensable for this purpose.
