Authors' conclusion

A positive association between baseline PRL and mortality was observed among patients with type 2 diabetes.

Study context

Population
Patients with T2DM with ≥2 prolactin measurements within 2 years of first inpatient diagnosis
Participants
10,907 patients
Exposure
Baseline serum prolactin (PRL) levels
Outcome
All-cause and CV mortality
Follow-up
Mean 5.34 years

Main finding

As reported in the abstract

All-cause and CV mortality by baseline PRL
Each group vs <100 mIU/LAdjusted hazard ratio (95% CI)
100-199 mIU/Lall-cause mortality
1.10(0.90–1.36)
200-299 mIU/Lall-cause mortality
1.35(1.11–1.67)
≥300 mIU/Lall-cause mortality
1.49(1.18–1.84)
100-199 mIU/LCV mortality
1.24(0.86–1.81)
200-299 mIU/LCV mortality
1.71(1.14–2.62)
≥300 mIU/LCV mortality
2.42(1.55–3.78)
Deaths
863
CV deaths
274

Observational data: associations, not effects.
