Long‐term all‐cause and cause‐specific mortality for four bariatric surgery procedures
Main finding · All-cause mortalityResult — go to the resultHazard ratio 0.84 95% CI 0.79–0.90Authors' conclusion
Reduced all-cause mortality was durable for multiple decades, for multiple bariatric surgical procedures, for females and males, and for greater than age 34 years at surgery. Rate of death from suicide was significantly higher in surgery versus non-surgery participants only in the youngest age at surgery participants.
