Diabetes, in‐hospital mortality trends and life expectancy loss among a 21.8‐million population in Beijing, China, 2012–2024
Authors' conclusion
Diabetes was associated with substantially higher in-hospital mortality and smaller mortality improvements. Earlier diagnosis was linked to greater life expectancy loss, with disproportionate losses among women.
