We read with interest the cross-sectional study by Li et al.1 on knowledge, attitude, and practice (KAP) toward low-salt diets among patients with chronic kidney disease (CKD) and their spouses/relatives in an outpatient nephrology setting (September 2023–February 2024). The authors should be commended for drawing attention to the often-overlooked household dimension of sodium restriction in CKD care. We would like to offer several considerations that may help refine interpretation and guide future research.
