Table 2 Coefficients resulting from the application of the mixture model to the perioperative AKI dataset. The column on the right represents the coefficients from subgroup V and are noticeably larger in absolute magnitude than those on the left

From: A general approach to risk modeling using partial surrogate markers with application to perioperative acute kidney injury
