GHR and diabetes mellitus: In the multivariable-adjusted Model, using the first quartile (Q1, 26 pre-DM events) of GHR as the reference group, HRs for progression to pre-DM were 1.518 (95% CI: 0.941–2.449) for the second quartile (Q2, 54 pre-DM events), 2.233 (95% CI: 1.411–3.532) for the third quartile (Q3, 90 pre-DM events), and 2.676 (95% CI: 1.674–4.278) for the fourth quartile (Q4, 141 pre-DM events).
