A nonsignificant delirium comparison can still leave clinically meaningful benefit or harm compatible with the data.
What the supplied source reports
Five randomized trials with 1,368 patients were included. The delirium risk ratio was 0.88, with a 95% confidence interval from 0.58 to 1.33. Hypotension was less frequent in the pooled remimazolam comparison, while postoperative nausea and vomiting did not differ significantly.
Limits of the evidence
The delirium interval includes both reduced and increased relative risk. Different delirium assessment methods and a limited trial pool restrict precision. The analysis therefore cannot establish equivalence simply because its probability value exceeded a conventional threshold.
Implications for expert analysis
For reporting, present the interval alongside the point estimate. Explain that the cardiovascular result addresses another endpoint and cannot narrow the delirium interval. This is particularly useful when an argument turns a statement that no difference was detected into a claim that cognitive effects must be the same.
