“there was no association between the type of anaesthetic agent and 1-yr mortality (hazard ratio=0.95; 95% confidence interval [CI] 0.84-1.08).”
None of its findings points the other way.

What is Inhalation anesthesia linked with?
3Studies link Inhalation anesthesia with 3 measures, most often acute kidney injury (1 study), perioperative adverse cardiovascular events (1) and postoperative pulmonary complications (1).
Acute kidney injury

Inhalation anesthesia raises the risk of acute kidney injury in humans (OR 2.19, 95% CI 1.88-2.57).

Inhalation anesthesia raises the risk of postoperative pulmonary complications in humans (OR 1.30, 95% CI 1.22-1.37).
“inhalation anaesthesia was associated with increased risk of postoperative complications (odds ratio [OR]=1.30; 95% CI 1.22-1.37 for postoperative pulmonary complications”
