Multiple linear regressions of mean number of GalNAc residues per HR on age, sex, race, MAP, eGFR, urinary protein level, and antihypertensive medication use (n = 59; consists of only patients with IgAN)
| Independent variable | Regression coefficient (95% confidence interval) | p value |
|---|---|---|
| Age (years) | 0.000 (−0.001 to 0.002) | 0.687 |
| Male (Ref: female) | −0.002 (−0.037 to 0.032) | 0.905 |
| Greek (Ref: Japanese) | −0.008 (−0.048 to 0.031) | 0.675 |
| MAP (mm Hg) | −0.002 (−0.003 to 0.000) | 0.021 |
| eGFR (ml/min/1.73 m2) | 0.001 (0.000 to 0.002) | 0.074 |
| Urinary protein (g/gCr) | −0.002 (−0.008 to 0.005) | 0.613 |
| Antihypertensive medication use, yes (Ref: no) | −0.023 (−0.062 to 0.016) | 0.239 |
GalNAc, N-acetylgalactosamine; HR, hinge region; IgAN, IgA nephropathy; HC, healthy control; MAP, mean arterial pressure; eGFR, estimated glomerular filtration rate.
