Mortality
mixedin humans1
Ridge-regularised multivariable model predicts mortality in humans (C-index 0.70 [0.65-0.74]; integrated calibration index 2.1% [1.3-6.4]).
“A parsimonious, ridge-regularised multivariable model developed in COPDGene showed good discrimination (C-index 0.70 [0.65-0.74]) and calibration (integrated calibration index 2.1% [1.3-6.4]) when validated in SUMMIT.”

Each roughly 25-millilitre increase in artery volume was linked to a death-rate ratio of 1.42 in one cohort and 1.23 in another.Each roughly 25-millilitre increase in artery volume was linked to a death-rate ratio of 1.42 in one cohort and 1.23 in another.
