Table 4. Association of Zn levels with the primary outcome in subgroups according to serum albumin levels.

	Adjusted HR (95% CI)	p
Low-albumin patients	3.31 (1.13, 9.70)	0.029
High-albumin patients	1.25 (0.63, 2.45)	0.52

Adjusted HRs of the low-Zn group to the high-Zn group are shown. HRs were adjusted for baseline characteristics, such as age, male sex, BMI, DM, cardiovascular disease, ln(eGFR), ln(CRP), serum albumin levels, hemoglobin levels, dipstick proteinuria, ARBs or ACE inhibitors, and diuretics.
