Table 2. Risk of Major Morbidities Comparing a Low-dose Opioid Regimen (Fast-track Cardiac Anesthesia) with a High-dose Opioid Regimen (Traditional Cardiac Anesthesia)

Not all relevant morbidity data were available in the original publications or from the authors. This is represented by the denominator of the incidence in each group.

* If the Slogoff trial 29is excluded, RR (95% CI) 0.91 (0.26–3.26), P = 0.89.

FTCA = fast-track cardiac anesthesia; ICU = intensive care unit; TCA = traditional cardiac anesthesia.
