Association of baseline levels of individual metalloproteinaises (MMPs) with all-cause mortality

MMP (ng/ml)

Hazard ratio (95% CI)

P

MMP-1

1.003 (0.99, 1.01)

0.3

MMP-2

1.0005 (0.99, 1.001)

0.7

MMP-3

0.999 (0.998, 1.000)

0.07

MMP-8

1.006 (1.002, 1.01)

0.003

MMP-9

1.005 (1.00, 1.001)

0.04

Separate Cox proportional hazard regression analyses were carried out for each MMP with adjustment for age, sex and disease duration at baseline.
