A higher K/Na ratio was associated with a higher socioeconomic status, as indicated by a significant trend towards higher education levels and a higher poverty-to-income ratio (PIR) across the quartiles (PIR: 3.04 ± 1.65 in Q4 vs 2.34 ± 1.59 in Q1, P < .001).
The discovery of a differential dose-response relationship: a non-linear, curvilinear association for AGP vs a linear 1 for log-CRP: is a subtle but highly significant finding.
While the trends for hypertension and diabetes prevalence did not reach statistical significance in the descriptive analysis, there was a pattern of lower prevalence in the higher K/Na ratio groups.
