- Period
2007-2012
- Sample size
26,173
4. Methods and endpoints

Patient/operative factors
- Comparator
Within cohort
- Endpoints
30-day serious complications; 90-day mortality
5. Actual results
- Results
Serious complications 3.4%; 90-day mortality 0.04%; intraoperative adverse event OR 2.63; conversion to open OR 4.12; learning curve OR 1.45.
- Absolute risks
90-day mortality 0.04%; serious complications 3.4%
- Authors' conclusion
Intraoperative adverse events and conversion are strongest risk factors; volume/experience matter.

- What the archive says about the study
Listed in the archive bibliography only; the archive gives no specific interpretation.
- A. What was actually studied?
Early complications
- B. What did the authors find?
3.4% serious; 0.04% 90-day mortality
- C. What conclusions do the authors themselves draw?
Experience matters
- D. What does the archive derive from it?
General complication list.
- E. Is this derivation scientifically justified?
Not applicable; the very low mortality contradicts 'lethal'.
