The HR of the variables included in the stepwise model were: male gender (HR = 1.84, 95% CI [0.90–3.75], p = 0.095), older age (per 1 year) (HR = 1.04, 95% CI [1.00–1.08], p = 0.031), hypertension (HR = 1.11, 95% CI [0.47–2.62], p = 0.804), renal failure (HR = 2.76, 95% CI [1.01–7.59], p = 0.048), insulin use (HR = 1.56, 95% CI [0.77–3.16], p = 0.212), admission for cardiovascular reasons (HR = 2.15, 95% CI [1.09–4.25], p = 0.027) and not having the habit of walking (HR = 0.57, 95% CI [0.25–1.31], p = 0.185). This evidence concerns the gene INS and acute kidney injury.
